Trustworthy electronic circuit protection expert
SMAJ-H Series
General Information
The SMA-H 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-H 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.
