TVS Diodes Datasheet SZP6SMB Series Surface Mount > 600W Pb RoHS e3 Description Bi-directional The SZP6SMB series is designed to protect voltage 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.
