This part carries AEC-Q101 qualification, making it suitable for automotive electronics where reliability under load-dump and inductive-switching surges is required. ## Clamping voltage and breakdown margin This margin ensures the TVS absorbs the surge energy without letting the protected rail exceed the downstream device's absolute maximum rating. The AEC-Q101 grade guarantees the part has passed the stress tests (H3TRB, temperature cycling, ESD) required for automotive PPAP submission. ## Through-hole axial package for high-reliability assembly Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE440AHB0G is supplied in bulk (loose parts). The through-hole form factor allows hand-soldering or wave-soldering and provides a robust mechanical connection for high-vibration applications. The bulk packaging is typical for MRO stock or low-volume production runs where tape-and-reel handling is not needed.","metaTitle":"1.5KE440AHB0G Taiwan Semi Zener TVS, 1500W, DO-201","metaDescription":"1.5KE440AHB0G Taiwan Semiconductor Zener TVS diode, 1500W peak pulse, 376V standoff, AEC-Q101 automotive grade, DO-201 axial.
