The breakdown voltage starts at 333V minimum, and the clamping voltage peaks at 482V at the rated pulse current of 3.2A. That 482V ceiling is what the downstream silicon sees — if your DC bus cap or downstream regulator is rated for 500V, this diode holds the transient below its absolute maximum. This is a single bidirectional channel — one DO-201 package handles positive and negative transients symmetrically. On a floating or bipolar rail you save a diode and a board spin compared to back-to-back unidirectional parts. ## Active production — no last-time-buy pressure Taiwan Semiconductor lists this part as Active. The DO-201AA (DO-27) axial package is through-hole — easy to hand-rework or replace on a prototype board. Pin 1 is the cathode band; the bidirectional marking is symmetrical, so orientation matters only for the banded end on the PCB silkscreen.","metaTitle":"1.5KE350CA R0G TVS Diode, 1500W, 300V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE350CA R0G bidirectional TVS diode, 1500W peak pulse power, 300V reverse standoff, 482V clamping.
