Features
The P6SMB11AT3G 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 P6SMB11AT3G 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.
