The SM8S Series TVS Diode utilizes an SMTO-263 package with lead modifications. It protects sensitive electronics against lightning and inductive load-switching voltage transient events. Features & Benefits ■7000 W peak pulse power capability at 10/1000 μs waveform, repetition rate (duty cycles):0.01 % ■SMTO-263 low-profile, surface-mount package minimizing PCB footprint and footprint is compatible with industrial popular DO-218AB package ■Typical failure mode is short from over-specified voltage or current ■Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c pass class 1/2 ■IEC 61000-4-2 ESD 30kV(Air), 30kV (Contact) ■Glass passivated chip junction ■Low dynamic resistance ■VBR @ TJ = VBR@25 °C x (1+αT x (TJ - 25))(αT:Temperature Coefficient, typical value is 0.1 % ■Recognized compound meeting flammability rating UL94V-0 ■Halogen-free and RoHS-compliant ■Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin (Sn) (IPC/JEDEC J-STD-609A.01) Applications TVS components are ideal for the protection of I/O interfaces, VCC bus and other vulnerable circuits in telecom, industrial and consumer applications.
