The 15.3 V typical reverse standoff voltage sets the working rail ceiling below which the device stays off and leakage is negligible; anything above that triggers the breakdown clamp. The 17.1 V minimum breakdown voltage marks where the Zener action definitively begins. ## Automotive qualification and thermal margin The -55°C to 175°C junction temperature range reflects that qualification grade. 175°C maximum junction temperature is well above most automotive thermal zones; a design running at 125°C ambient still has 50°C of junction margin before the limit — which matters for engine-bay and direct-radiator board placements. Tape-and-reel packaging supports automated insertion on axial lead machines; the through-hole leads require board mounting holes sized for standard DO-201AA lead gauges and a solder joint profile compatible with the through-hole process. ## Sourcing posture and lifecycle Listed Active — no official successor or cross-reference appears in the manufacturer record on file. For a new design, confirm the current NCNR status and minimum order quantity with the supplier before committing to the BOM line.","metaTitle":"Vishay 1N6277AHE3_A/C Zener TVS, 1500W, AEC-Q101, DO-201AA","metaDescription":"Vishay 1N6277AHE3_A/C unidirectional Zener TVS, 15.3V standoff, 25.2V clamping, 1500W peak pulse, AEC-Q101, -55°C to 175°C junction.
