TVS Diodes Surface Mount > 200W > SMF5.0AT1G Series SMF5.0AT1G Series Pb OBSOLETE/EOL Description DATE June/30/2018 PCN/ECN# LFPCN41246 REPLACED BY SMF Series The SMF5.0AT1G Series is designed to protect voltage sensitive components from high voltage, high energy transients. Excellent clamping capability, high surge capability, low zener impedance and fast response time. Because of its small size, it is ideal for use in cellular phones, portable devices, business machines, power supplies and many other industrial/consumer applications.
