Product details

1500 W peak pulse, bidirectional clamping

The 1.5KE480CA-B: The 1500 W rating means it absorbs a 1 ms surge without failing — useful for industrial power supplies, motor drives, and telecom rectifiers where the transient energy is high but the duty cycle is low.

Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE480CA-B mounts through-hole on a PCB or terminal block. The bidirectional channel means a single device replaces two unidirectional diodes in anti-series, saving board space and reducing parts count on a bipolar rail or AC line.
