SZSMF10AT1G

TVS Diodes Surface Mount > 200W > SZSMF Series SZSMF Series Pb e3 RoHS Description Uni-Directional The SZSMF series is designed to protect sensitive systems or components from high voltage, high energy transients. It offers a fast response time, low Zener impedance, high surge and excellent clamping capabilities. Because of its small size, it is ideal for use in cellular phones, portable devices, business machines, power supplies and other industrial and consumer applications.
