Datasheet
RClamp0502BA Ultra-Low Capacitance TVS for ESD and CDE Protection ## PROTECTION PRODUCTS - RailClamp **[®]** ## Description RailClamp[®] TVS diodes are specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (cable discharge events), and EFT (electrical fast transients). The RClamp[®] 0502BA has a typical capacitance of only 0.60pF (pin 1 to 2). This means it can be used on circuits operating in excess of 3GHz with minimal signal attenuation. They may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge). Each device can be configured to protect 1 bidirectional line or two unidirectional lines. These devices are in a small SC-75 (SOT-523) package and feature a lead-free, matte tin finish. They are compatible with both lead free and SnPb assembly techniques. They are designed for use in applications where board space is at a premium. The combination of small size, low capacitance, and high level of ESD protection makes them a flexible solution for applications such as HDMI, MDDI, antenna circuits, Automatic Test Equipment, USB 2.0, and Infiniband circuits. ## Features - Transient protection for high-speed data lines to IEC 61000-4-2 (ESD) ±18kV (air), ±12kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) - Protects up to two I/O lines - Ultra-Low capacitance (<1pF) - No insertion loss to **>3.0GHz** - Low profile (<1mm) - Low leakage current and clamping voltage - Low operating voltage: 5.0V - Solid-state silicon-avalanche technology ## Mechanical Characteristics - SC-75 (SOT-523) package - Lead Finish: Matte Tin - Pb-Free, Halogen Free, RoHS/WEEE Compliant - Molding compound flammability rating: UL 94V-0 - Packaging: Tape and Reel ## Applications - Mobile Display Digital Interface (MDDI) - USB 2.0 - Firewire Ports - GaAs Photodetector Protection - HBT Power Amp Protection - Infiniband Transceiver Protection ## Dimensions **==> picture [265 x 209] intentionally omitted <==** **----- Start of picture text -----**<br> 1.60<br>0.50 BSC<br>3<br>1.60<br>0.80<br>1 2<br>1.00<br>BSC<br>0.75<br>Nominal Dimensions (mm)<br>**----- End of picture text -----**<br> ## Schematic & PIN Configuration **==> picture [264 x 209] intentionally omitted <==** **----- Start of picture text -----**<br> SC-75 3L (Top View)<br>**----- End of picture text -----**<br> www.semtech.com Revision 4/19/2010 1 ## RClamp0502BA ## PROTECTION PRODUCTS ## Absolute Maximum Rating |PROTECTION PRODUCTS<br>Absolute Maximum Rating|||| |---|---|---|---| |g<br>n<br>it<br>a<br>R|l<br>o<br>b<br>m<br>y<br>S|e<br>ul<br>a<br>V|s<br>ti<br>n<br>U| |)s<br>μ<br>0<br>2<br>/<br>8<br>=<br>p<br>t(<br>r<br>e<br>w<br>o<br>P<br>e<br>slu<br>P<br>k<br>a<br>e<br>P|P k<br>p|5<br>2<br>1|stt<br>a<br>W| |)s<br>μ<br>0<br>2<br>/<br>8<br>=<br>p<br>t(<br>t<br>n<br>e<br>rr<br>u<br>C<br>e<br>slu<br>P<br>k<br>a<br>e<br>P|I P<br>P|5|A| |)riA<br>(<br>2<br>-<br>4<br>-<br>0<br>0<br>0<br>1<br>6<br>C<br>EI<br>r<br>e<br>p<br>D<br>S<br>E<br>)tc<br>a<br>t<br>n<br>o<br>C<br>(<br>2<br>-<br>4<br>-<br>0<br>0<br>0<br>1<br>6<br>C<br>EI<br>r<br>e<br>p<br>D<br>S<br>E|V<br>D<br>S<br>E|8<br>1<br>2<br>1|V<br>k| |e<br>r<br>u<br>t<br>a<br>r<br>e<br>p<br>m<br>e<br>T<br>g<br>nit<br>a<br>r<br>e<br>p<br>O|TJ|5<br>2<br>1<br>+<br>o<br>t<br>5<br>5<br>-|C<br>°| |e<br>r<br>u<br>t<br>a<br>r<br>e<br>p<br>m<br>e<br>T<br>e<br>g<br>a<br>r<br>o<br>t<br>S|T<br>G<br>T<br>S|0<br>5<br>1<br>+<br>o<br>t<br>5<br>5<br>-|C<br>°| ## Electrical Characteristics (T=25[o] C) |Electrical Characteristics (T=25oC)|Electrical Characteristics (T=25oC)|Electrical Characteristics (T=25oC)|Electrical Characteristics (T=25oC)|Electrical Characteristics (T=25oC)|Electrical Characteristics (T=25oC)|Electrical Characteristics (T=25oC)| |---|---|---|---|---|---|---| |||||||| |r<br>e<br>t<br>e<br>m<br>a<br>r<br>a<br>P|l<br>o<br>b<br>m<br>y<br>S|s<br>n<br>oiti<br>d<br>n<br>o<br>C|m<br>u<br>m<br>i<br>ni<br>M|l<br>a<br>ci<br>p<br>y<br>T|m<br>u<br>m<br>ix<br>a<br>M|s<br>ti<br>n<br>U| |e<br>g<br>a<br>tlo<br>V<br>ff<br>O<br>-<br>d<br>n<br>a<br>t<br>S<br>e<br>sr<br>e<br>v<br>e<br>R|V<br>M<br>W<br>R|3<br>niP<br>o<br>t<br>2<br>niP<br>r<br>o<br>1<br>niP<br>2<br>d<br>n<br>a<br>1<br>s<br>niP<br>n<br>e<br>e<br>w<br>t<br>e<br>B<br>d<br>n<br>a|||5|V| |e<br>g<br>a<br>tlo<br>V<br>n<br>w<br>o<br>d<br>k<br>a<br>e<br>r<br>B<br>e<br>sr<br>e<br>v<br>e<br>R|V R<br>B|It<br>A<br>m<br>1<br>=<br>3<br>niP<br>o<br>t<br>2<br>niP<br>r<br>o<br>1<br>niP<br>2<br>d<br>n<br>a<br>1<br>s<br>niP<br>n<br>e<br>e<br>w<br>t<br>e<br>B<br>d<br>n<br>a|6|||V| |t<br>n<br>e<br>rr<br>u<br>C<br>e<br>g<br>a<br>k<br>a<br>e<br>L<br>e<br>sr<br>e<br>v<br>e<br>R|IR|V<br>M<br>W<br>R<br>C<br>°<br>5<br>2<br>=<br>T<br>,V<br>5<br>=<br>3<br>niP<br>o<br>t<br>2<br>niP<br>r<br>o<br>1<br>niP<br>2<br>d<br>n<br>a<br>1<br>s<br>niP<br>n<br>e<br>e<br>w<br>t<br>e<br>B<br>d<br>n<br>a|||1|A<br>μ| |e<br>g<br>a<br>tlo<br>V<br>g<br>nip<br>m<br>alC|VC|I P<br>P<br>s<br>μ<br>0<br>2<br>/<br>8<br>=<br>p<br>t<br>,<br>A<br>1<br>=<br>2<br>niP<br>o<br>t<br>1<br>niP|||5<br>1|V| |e<br>g<br>a<br>tlo<br>V<br>g<br>nip<br>m<br>alC|VC|I P<br>P<br>s<br>μ<br>0<br>2<br>/<br>8<br>=<br>p<br>t<br>,<br>A<br>5<br>=<br>3<br>niP<br>o<br>t<br>2<br>niP<br>r<br>o<br>1<br>niP|||2<br>2|V| |e<br>g<br>a<br>tlo<br>V<br>g<br>nip<br>m<br>alC|VC|I P<br>P<br>s<br>μ<br>0<br>2<br>/<br>8<br>=<br>p<br>t<br>,<br>A<br>5<br>=<br>2<br>niP<br>o<br>t<br>1<br>niP|||5<br>2|V| |e<br>c<br>n<br>a<br>tic<br>a<br>p<br>a<br>C<br>n<br>oitc<br>n<br>u<br>J|Cj|VR<br>z<br>H<br>M<br>1<br>=<br>f<br>,V<br>0<br>=<br>2<br>niP<br>o<br>t<br>1<br>niP||0<br>6<br>.<br>0|9<br>.<br>0|F<br>p| |e<br>c<br>n<br>a<br>tic<br>a<br>p<br>a<br>C<br>n<br>oitc<br>n<br>u<br>J|Cj|VR<br>z<br>H<br>M<br>1<br>=<br>f<br>,V<br>0<br>=<br>3<br>niP<br>o<br>t<br>2<br>niP<br>r<br>o<br>1<br>niP|||2<br>.<br>1|F<br>p| www.semtech.com © 2010 Semtech Corp. 2 RClamp0502BA ## PROTECTION PRODUCTS ## Typical Characteristics ## Non-Repetitive Peak Pulse Power vs. Pulse Time **==> picture [234 x 156] intentionally omitted <==** **----- Start of picture text -----**<br> 10<br>1<br>0.1<br>0.01<br>0.1 1 10 100 1000<br>Pulse Duration -

RClamp0502BA ## PROTECTION PRODUCTS ## Applications Information ## Device Connection Options ## Figure 1. Pin Configuration This device is optimized for protection of 1 line operating in excess of 3GHz. It may also be used to protect two lines operating in excess of 2.0GHz. The device is connected as follows: Protection for one line with <1pF capacitance can be achieved by connecting one data line to either pin 1 or pin 2 with the other pin connected to ground. Pin 3 is not connected. The connection to ground should be made directly to a ground plane. The path length should also be kept as short as possible to minimize parasitic inductance. Protection of two lines is achieved by connecting data lines at pins 1 & 2. Pin 3 is connected to ground. The connection to ground should be made directly to a ground plane. The path length should also be kept as short as possible to minimize parasitic inductance. ## 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 © 2010 Semtech Corp. 5 ## RClamp0502BA ## PROTECTION PRODUCTS ## Outline Drawing -SC-75 (SOT-523) **==> picture [311 x 250] intentionally omitted <==** **----- Start of picture text -----**<br> A D DIMENSIONS<br>INCHES MILLIMETERS<br>e1 DIM MIN NOM MAX MIN NOM MAX<br>B A .023 - .035 0.60 - 0.90<br>3 A1 .000 - .004 0.00 - 0.10<br>A2 .023 .030 .031 0.60 0.75 0.80<br>b .005 - .012 0.15 - 0.30<br>c .003 - .008 0.10 - 0.20<br>E1 E D .059 .063 .067 1.50 1.60 1.70<br>E .057 .063 .069 1.45 1.60 1.75<br>E1 .029 .031 .033 0.75 0.80 0.85<br>e .039 BSC 1.00 BSC<br>1 2 e1 .020 BSC 0.50 BSC<br>L (.009) (0.22)<br>bxN N 3 3<br>e bbb C A B aaa 0 0° .004- 8° 0° 0.10- 8°<br>bbb .008 0.20<br>A A2 aaa C<br>SEATING PLANE<br>A1 C<br>H<br>SEE DETAIL A<br>0 c<br>SEATING<br>PLANE<br>C<br>L<br>SIDE VIEW DETAIL A<br>NOTES:<br>**----- End of picture text -----**<br> 1.
