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.
