## RClamp0508M RailClamp **[]** Low Capacitance TVS Diode Array ## PROTECTION PRODUCTS - RailClamp ## Description RailClamps are surge rated diode arrays designed to protect high speed data interfaces. The RClamp series has been specifically designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (cable discharge events), EFT (electrical fast transients), and lightning. The unique design of these devices incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. During transient conditions, the steering diodes direct the transient to either the positive side of the power supply line or to ground. The internal TVS diode prevents over-voltage on the power line, protecting any downstream components. The RClamp[TM] 0508M has a low typical capacitance of 3pF and may be used on lines operating up to 1GHz. This makes the device ideal for protection of highspeed data lines such as USB 2.0, Firewire, DVI, and gigabit Ethernet interfaces. The low capacitance array configuration allows the user to protect eight high-speed data or transmission lines. The low inductance construction minimizes voltage overshoot during high current surges. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV contact discharge). ## Features - ESD protection for high-speed data lines to IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) IEC 61000-4-5 (Lightning) 12A (8/20µs) -

RClamp0508M ## PROTECTION PRODUCTS ## Applications Information ## Device Connection Options for Protection of Eight High-Speed Data Lines This device is designed to protect eight data lines from transient over-voltages by clamping them to a fixed reference. When the voltage on the protected line exceeds the reference voltage (plus diode VF) the steering diodes are forward biased, conducting the transient current away from the sensitive circuitry. Data lines are connected at pins 1, 2, 4, 5, 7, 8, 9, and 10. The negative reference is connected at pin 6. This pin should be connected directly to a ground plane on the board for best results. The path length is kept as short as possible to minimize parasitic inductance. The positive reference is connected at pin 3. The options for connecting the positive reference are as follows: 1. To protect data lines and the power line, connect pin 3 directly to the positive supply rail (VCC). In this configuration the data lines are referenced to the supply voltage. The internal TVS diode prevents over-voltage on the supply rail. 2. In applications where the supply rail does not exit the system, the internal TVS may be used as the reference. In this case, pin 3 is not connected. The steering diodes will begin to conduct when the voltage on the protected line exceeds the working voltage of the TVS (plus one diode drop). ## Schematic **==> picture [254 x 112] intentionally omitted <==** **----- Start of picture text -----**<br> 3<br>1 2 4 5 7 8 9 10<br>6<br>**----- End of picture text -----**<br> ## Pin Configuration **==> picture [243 x 110] intentionally omitted <==** **----- Start of picture text -----**<br> Line 1 1 Line 8<br>Line 2 Line 7<br>Vcc Line 6<br>Line 3 Line 5<br>Line 4 GND<br>**----- End of picture text -----**<br> ## Universal Serial Bus ESD Protection The RClamp0508M may be used to protect USB 2.0 ports on monitors, computers, peripherals or portable systems. Each device will protect up to four USB ports. When the voltage on the data lines exceed the bus voltage (plus one diode drop), the internal rectifiers are forward biased conducting the transient current away from the protected controller chip. The TVS diode directs the surge to ground. The TVS diode also acts to suppress ESD strikes directly on the voltage bus. Thus, both power and data pins are protected with a single device. www.semtech.com 2008 Semtech Corp. 5 RClamp0508M ## PROTECTION PRODUCTS ## Applications Information ## ESD Protection With RailClamps **[]** RailClamps are optimized for ESD protection using the rail-to-rail topology. They are designed to overcome the inherent disadvantages of using discrete signal diodes for ESD suppression. The RailClamp’s integrated TVS diode helps to mitigate the effects of parasitic inductance in the power supply connection. During an ESD event, the current will be directed through the integrated TVS diode to ground. The maximum voltage seen by the protected IC due to this path will be the clamping voltage of the device. The line loading capacitance is minimized by using low capacitance steering diodes. The steering diodes are scaled to handle high current ESD events without damage or degradation. The end result is a highly reliable, integrated solution that eliminates the guess work associated with using discrete components. ## **Rail-To-Rail Protection Using RailClamp TVS Arrays** **==> picture [207 x 101] intentionally omitted <==** ## Matte Tin Lead Finish Matte tin has become the industry standard lead-free replacement for SnPb lead finishes. A matte tin finish is composed of 100% tin solder with large grains. Since the solder volume on the leads is small compared to the solder paste volume that is placed on the land pattern of the PCB, the reflow profile will be determined by the requirements of the solder paste. Therefore, these devices are compatible with both lead-free and SnPb assembly techniques. In addition, unlike other lead-free compositions, matte tin does not have any added alloys that can cause degradation of the solder joint. www.semtech.com 2008 Semtech Corp. 6 RClamp0508M ## PROTECTION PRODUCTS ## Applications Information - SPICE Model **==> picture [279 x 179] intentionally omitted <==** **----- Start of picture text -----**<br> 1.0 nH<br>I/O Line<br>nH<br>**----- End of picture text -----**<br> RClamp0508M Spice Model |s<br>r<br>e<br>t<br>e<br>m<br>a<br>r<br>a<br>P<br>e<br>ci<br>p<br>S<br>M<br>8<br>0<br>5<br>0<br>p<br>m<br>al<br>C<br>R|s<br>r<br>e<br>t<br>e<br>m<br>a<br>r<br>a<br>P<br>e<br>ci<br>p<br>S<br>M<br>8<br>0<br>5<br>0<br>p<br>m<br>al<br>C<br>R|s<br>r<br>e<br>t<br>e<br>m<br>a<br>r<br>a<br>P<br>e<br>ci<br>p<br>S<br>M<br>8<br>0<br>5<br>0<br>p<br>m<br>al<br>C<br>R|s<br>r<br>e<br>t<br>e<br>m<br>a<br>r<br>a<br>P<br>e<br>ci<br>p<br>S<br>M<br>8<br>0<br>5<br>0<br>p<br>m<br>al<br>C<br>R|s<br>r<br>e<br>t<br>e<br>m<br>a<br>r<br>a<br>P<br>e<br>ci<br>p<br>S<br>M<br>8<br>0<br>5<br>0<br>p<br>m<br>al<br>C<br>R| |---|---|---|---|---| |r<br>e<br>t<br>e<br>m<br>a<br>r<br>a<br>P|ti<br>n<br>U|)<br>D<br>R<br>C<br>L<br>(<br>1<br>D|)<br>D<br>R<br>C<br>L<br>(<br>2<br>D|)<br>S<br>V<br>T<br>(<br>3<br>D| |S<br>I|p<br>m<br>A|4<br>1<br>-<br>E<br>0<br>1|4<br>1<br>-<br>E<br>0<br>1|4<br>1<br>-<br>E<br>0<br>1| |V<br>B|tlo<br>V|0<br>8<br>1|0<br>2|9<br>5<br>.<br>8| |J<br>V|tlo<br>V|2<br>6<br>.<br>0|9<br>5<br>.<br>0|6<br>.<br>0| |S<br>R|m<br>h<br>O|1<br>3<br>.<br>0|7<br>3<br>.<br>0|0<br>0<br>5<br>.<br>0| |V<br>B<br>I|p<br>m<br>A|3<br>-<br>E<br>1|3<br>-<br>E<br>1|3<br>-<br>E<br>1| |O<br>J<br>C|d<br>a<br>r<br>a<br>F|2<br>1<br>-<br>E<br>3|2<br>1<br>-<br>E<br>1|2<br>1<br>-<br>E<br>0<br>6<br>3| |T<br>T|c<br>e<br>s|9<br>-<br>E<br>1<br>4<br>5<br>.<br>2|9<br>-<br>E<br>1<br>4<br>5<br>.<br>2|9<br>-<br>E<br>1<br>4<br>5<br>.<br>2| |M|--|1<br>0<br>.<br>0|1<br>0<br>.<br>0|4<br>3<br>3<br>.<br>0| |N|--|1.<br>1|1.<br>1|1.<br>1| |G<br>E|V<br>e|1<br>1.<br>1|1<br>1.<br>1|1<br>1.<br>1| www.semtech.com 2008 Semtech Corp. 7 RClamp0508M ## PROTECTION PRODUCTS ## Outline Drawing - MSOP 10LOutline Drawing - SO-8 **==> picture [477 x 202] intentionally omitted <==** **----- Start of picture text -----**<br> DIMENSIONS<br>e<br>INCHES MILLIMETERS<br>A D DIM MIN NOM MAX MIN NOM MAX<br>A - - .043 - - 1.10<br>N A1 .000 - .006 0.00 - 0.15<br>SEE DETAIL A A2 .030 - .037 0.75 - 0.95<br>2X E/2 SIDE VIEW b .007 - .011 0.17 - 0.27<br>c .003 - .009 0.08 - 0.23<br>E1 E D .114 .118 .122 2.90 3.00 3.10<br>PIN 1 E1 .114 .118 .122 2.90 3.00 3.10<br>INDICATOR H E .193 BSC 4.90 BSC<br>e .020 BSC 0.50 BSC<br>L .016 .024 .032 0.40 0.60 0.80<br>ccc C 1 2 GAGE c L1 (.037) (.95)<br>2X N/2 TIPS B PLANE 01N 0° 10- 8° 0° 10- 8°<br>aaa .004 0.10<br>0.25 L 01 bbb .003 0.08<br>(L1) ccc .010 0.25<br>D<br>aaa C DETAIL A<br>A2 A<br>SEATING<br>PLANE<br>C A1<br>bxN<br>bbb C A-B D<br>**----- End of picture text -----**<br> NOTES: 1.

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
