When the line transient exceeds the 8.55 V standoff, the device breaks down at the 9.5 V minimum threshold and clamps at 14.5 V maximum — the clamping voltage is the ceiling the downstream circuitry sees. ## Automotive grade and thermal margin The -55°C to 175°C junction temperature range gives wide margin against the under-hood hot end; the 175°C ceiling is the derating floor, not a marketing headroom claim. ## Sourcing the obsolete part number Confirm the full series variant and the exact voltage hold-off window before committing to a BOM line.","metaTitle":"Vishay 1N6271AHE3/51 TVS Diode, 1500W Peak Pulse, DO-201AA","metaDescription":"Vishay 1N6271AHE3/51 unidirectional TVS Zener, AEC-Q101, 1500W peak pulse, 14.5V clamping.
