SMAJ Transient Voltage Suppressor Diode Series

General Information

The SMA series is designed to protect voltage sensitive components from high

voltage, high energy transients. They have excellent clamping capability, high surge

capability, low zener impedance and fast response time. The SMA 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.

Features
