Mounted on copper pad area of 0.2x0.2” (5.0 x 5.0mm) to each terminal. 3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional device only, duty cycle=4 per minute maximum. 4. VF < 3.5V for single die parts and VF< 5.0V for stacked-die parts. 5. The PPPM of stacked-die parts is 800W and please contact littelfuse for the detail stacked-die parts. **Description** The SMBJ is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. ~~oO~~ ## **Features** Lo - 600W peak pulse power • Built-in strain relief capability at 10/1000μs • Fast response time: waveform, repetition rate typically less than 1.0ps (duty cycles):0.01% from 0V to BV min - Excellent clamping • High temperature capability to reflow soldering - • Low incremental surge guaranteed: 260°C/40sec resistance • VBR @ TJ= VBR@25°C - • Typical IR less than 1μA x (1+αT x (TJ - 25)) when VBR min>12V (αT:Temperature - • For surface mounted Coefficient, typical value applications to optimize is 0.1%) board space • Plastic package is - • Low profile package flammability rated V-0 per Underwriters Laboratories - • Typical failure mode is short from over-specified • Meet MSL level1, per voltage or current J-STD-020, LF maximun - • Whisker test is conducted peak of 260°C based on JEDEC • Matte tin lead–free plated JESD201A per its table 4a • Halogen free and RoHS and 4c compliant - IEC-61000-4-2 ESD • Pb-free E3 means 2nd 30kV(Air), 30kV (Contact) level interconnect is - • ESD protection of data Pb-free and the terminal lines in accordance with finish material is tin(Sn) IEC 61000-4-2 (IPC/JEDEC J-STD- - EFT protection of data 609A.01) lines in accordance with IEC 61000-4-4 ## **Applications** Po TVS devices are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Telecom, Computer, Industrial and Consumer electronic applications. **==> picture [499 x 116] intentionally omitted <==** **----- Start of picture text -----**

For bidirectional type having VR of 10 volts and less, the IR limit is double.
For parts without A , the VFor parts with “*” are made by stack chip, which has higher surge capability (typical 1.8*IPP as specified).BR is ± 10% and VC is 5% higher than with A parts. © 2016 Littelfuse, Inc.
