Its 376V reverse standoff voltage means it stays out of circuit during normal 376V DC bus operation; the breakdown starts at 418V minimum, and the clamping voltage peaks at 776V at the rated 13A peak pulse current. That protection window — standoff, breakdown, clamp — is the full envelope a power rail designer needs to check against the transient immunity of the downstream silicon. ## DO-201AA axial — field-swappable with pliers Through-hole DO-201 axial package. No hot-air station needed — a soldering iron and a pair of flush cutters swap this part on a customer site. The body is keyed by the banded cathode end on the unidirectional version; the bidirectional 1.5KE440CARL has no polarity marking because it does not need one. That saves a reverse-insertion mistake on a board swap. STMicroelectronics lists the 1.5KE440CARL as obsolete.","metaTitle":"1.5KE440CARL 1500W TVS, 376V Standoff, DO-201, Obsolete","metaDescription":"1.5KE440CARL is a 1500W bidirectional Zener TVS from STMicroelectronics, 376V reverse standoff, 418V min breakdown, 776V clamp.
