Littelfuse SZ1SMA 400W TVS Diodes

Littelfuse SZ1SMA 400W TVS Diodes are unidirectional and bidirectional devices designed to protect voltage-sensitive electronics from high-voltage, high-energy transients. Littelfuse SZ1SMA TVS Diodes have high clamping capability and high surge capability as well as low zener impedance and fast response time (<1ns typical). Littelfuse SZ1SMA comes in a cost-effective, high-reliability package and is ideal for use in communication systems, automotive, medical equipment, and more.
