Typical peak pulse power: – 400 W (10/1000 µs) – 2.4 kW (8/20 µs) Stand off voltage range: from 5 V to 33 V Unidirectional types Low leakage current: – 0.2 µA at 25 °C – 1 µA at 85 °C Operating T j max: 175 °C JEDEC registered package outline RoHS package Halogen free molding compound Complies with the following standards IEC 61000-4-2 level 4: – 15 kV (air discharge) – 8 kV (contact discharge) MIL STD 883G-Method 3015-7: class3 – 25 kV (human body model)

Description

The SMM4F Transil series has been designed to protect sensitive equipment against electro-static discharges according to IEC 61000-4-2, MIL STD

883 Method 3015, and electrical over stress such

as IEC 61000-4-4 and 5. They are generally for surges below 400 W 10/1000 µs. This planar technology makes it compatible with high-end equipment and SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time. Their low clamping voltages provide a better safety margin to protect sensitive circuits with extended life time expectancy. Packaged in STmite flat, this minimizes PCB space consumption (footprint in accordance with IPC 7531 standard). K A STmite flat (DO222-AA) www.shunyegroup.com.cn
