SMM4F18A

SMM4F High junction temperature Transil™ Features ■ Typical peak pulse power: www.DataSheet4U.com – 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 Tj max: 175 °C JEDEC registered package outline RoHS package Halogen free molding compound K STmite flat (DO222-AA) A ■ ■ ■ ■ 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). ■ TM: Transil is a trademark of STMicroelectronics December 2007 Rev 2 1/10 www.st.com 10 Characteristics SMM4F 1 Characteristics Table 1.
