Product details

Device identity and protection role

The 1.5KE120C: The maximum clamping voltage of 173.25V at 9.2A peak pulse current defines the highest voltage the protected circuit will see during a surge event.

Package and mounting for through-hole assembly

Housed in a DO-201AA / DO-27 axial-lead package, the 1.5KE120C is a through-hole component. The DO-201 body is common for 1.5kW TVS diodes and mates with standard 0.040-inch diameter lead holes on a PCB. The axial leads allow either vertical or horizontal mounting depending on board layout constraints. Supplied in Tape & Reel packaging, the part is compatible with automated insertion equipment for volume assembly.
