SMCLCE-HR/HRA 1,500 W Low-Capacitance Surface-Mount TVS Diodes
Littelfuse high-reliability diodes have a low-profile package ideal for surface-mounted avionics applications

Littelfuse SMCLCE-HR and SMCLCE-HRA series high-reliability surface-mount TVS diodes are designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. TVS components are ideal for the protection of I/O interfaces, VCC bus, and other vulnerable circuits used in telecom, computer, industrial, and consumer electronic applications.
