The DO-201AA axial package is a through-hole form factor suitable for point-of-use transient suppression on power input lines or high-side bus rails where board space is not the constraint. Reverse standoff voltage is 28.2V — the TVS does not conduct at normal bus voltage up to that level. Breakdown starts at 31.4V minimum, so a 28V rail with ±5% tolerance stays below the conduction threshold. Maximum clamping voltage is 45.7V at 34A peak pulse current (10/1000µs waveform). That 45.7V ceiling protects downstream 40V-rated MOSFETs or regulators from avalanche stress during a load-dump or inductive kickback event. Single unidirectional channel — polarity matters; the cathode band on the DO-201AA body must face the rail being protected. No power line protection feature means the diode does not filter continuous overvoltage; it only clamps fast transients. ## Sourcing and lifecycle status No direct stock-holding claim — availability is verified per request.","metaTitle":"1.5KE33AHE3_B/C Vishay TVS Zener, 1500W, 28.2V, DO-201AA","metaDescription":"Vishay 1.5KE33AHE3_B/C 1500W Zener TVS, 28.2V standoff, 45.7V clamp, AEC-Q101 automotive grade.
