SMF5.0AT1G Series,

SZSMF5.0AT1G Series

200 W Transient

Voltage Suppressor

SOD-123 Flat Lead Package

Littelfuse.com

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.
