Product Details
The SMM4F Transil series has been designed to protect sensitive equipment against electrostatic discharges and electrical over stress. 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. Transil is a trademark of STMicroelectronics.
