At that pulse the clamping voltage sits at 15.6 V maximum while the device clamps 96.2 A through the transient, which means the suppressor conducts hard and diverts the surge energy away from whatever circuit sits behind it rather than letting the spike propagate. The reverse standoff is 9.4 V typical, so the TVS sits passively below that threshold and activates only when the line exceeds the breakdown minimum of 10.5 V. AEC-Q101 qualification places this in the automotive supply chain — the transzorB® series is a Vishay trademark for their glass-passivated Zener TVS construction, and the qualification covers the temperature cycling, humidity bias, and surge life testing required by tier-one ECU programs. ## 175 °C junction rating and the DO-201AA form factor Junction temperature ceiling is 175 °C with a rated operating range down to −55 °C, which covers the under-hood hot side of the automotive thermal band. The DO-201AA (also referenced as DO-27) is a through-hole axial package — the lead diameter and body length suit board-mounting in automotive control modules where the PCB is potted or conformal-coated. The Supplier Device Package field lists 1.5KE, which is Vishay's standard case size for this power class. ## Obsolete — sourcing reality and what is on record The base product root is 1N6272, so cross-reference searches for that family may surface the next-generation automotive TVS — but any substitute must be validated for standoff, clamping, and peak pulse ratings against the actual application surge environment, not just the order code match.","metaTitle":"Vishay 1N6272AHE3/51 Zener TVS Diode, 1500W Peak","metaDescription":"1N6272AHE3/51 — Vishay Automotive AEC-Q101 TransZorb, unidirectional TVS, 1500W peak pulse, DO-201AA.
