SZP6SMB Series
Description
The SZP6SMB series is designed to protect voltage
Bi-directional
sensitive components from high voltage, high energy
transients. They have excellent clamping capability, high
surge capability, low breakdown impedance and fast
response time. The SZP6SMB series is supplied in the
Littelfuse exclusive, cost-effective, highly reliable package
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.
