1 SMF.TG Series Pb OBSOLETE/EOL Description DTE June/3/8 PCN/ECN# LFPCN446 REPLCED BY SMF Series The SMF.TG 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. Features Stand off Voltage: 8 Volts Peak Power ms (SMF.
