SZ1.5SMC 1500W TVS Diodes

Littelfuse SZ1.5SMC 1500W TVS Diodes are designed to protect voltage-sensitive components. The series offers protection from high-voltage and high-energy transients. The diodes have excellent clamping capability, high surge capability, low Zener impedance, and fast response time. The diodes offer a working peak reverse voltage range of 5.8V to 77.8V, a standard Zener breakdown voltage range of 6.45V to 95.5V, and 1500W at 1ms peak power. Applications for Littelfuse SZ1.5SMC 1500W TVS Diodes include communication systems, automotive, numerical controls, process controls, medical equipment, business machines, and power supplies.
