SMM4F12AVCL中文资料400 W low clamping voltage Transil™数据手册ST规格书

描述 Description

The SMM4F12AVCL 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 such as HDD power combo voltage regulators.
Packaged in STmite flat, this minimizes PCB space consumption (footprint in accordance with IPC 7531 standard).
