The standoff voltage is 376 V, so the diode does not conduct at normal line voltage below that level; breakdown starts at 418 V minimum. ## DO-201AA axial — through-hole fit and temperature range Housed in a DO-201AA (DO-27) axial leaded package, this is a through-hole part — it solders into a board with leads bent and trimmed, or mounts in a terminal block for high-reliability power supplies and industrial controls. The operating junction temperature range spans -55°C to 175°C, covering cold-start environments and hot enclosures alike. It is a single unidirectional channel — cathode band marked — so polarity matters on the board; reverse connection forward-biases the Zener and defeats the clamping. ## Sourcing and compliance documentation The base product number is 1.5KE440; the -/54 suffix indicates the lead-free / RoHS-compliant finish and the tape-and-reel packaging option (TR).","metaTitle":"Vishay 1.5KE440A-E3/54 TransZorb TVS, 1500W, 602V Clamp","metaDescription":"Active Vishay 1.5KE440A-E3/54 Zener TVS diode, 1500W peak pulse, 602V clamping, DO-201AA axial.
