SMF Transient Voltage Suppressor Diode Series

General Information

The SMF 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 SMF 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.
