SMAF Transient Voltage Suppressor Diode Series

General Information

The SMAF series is designed specifically to protect sensitive electronic

equipment from voltage transients induced by lightning and other transient voltage

events. They have excellent clamping capability, high surge capability, low zener

impedance and fast response time. The SMAF series is supplied in YINT

Semiconductor’s exclusive, cost-effective, highly reliable and is ideally suited for use

in communication systems, automotive, numerical controls , process controls,

medical equipment, business machines, power supplies and many other

industrial/consumer Applications.
