At that peak pulse, the clamping voltage tops out at 10.5 V while the reverse standoff sits at 5.8 V typical, giving roughly 1.8× protection margin between normal operation and the clamp ceiling. ## Temperature range and general-purpose deployment Junction temperature range runs from -55 °C to 175 °C — the wide high end makes this suitable for equipment that sees significant self-heating, and the low end covers outdoor or cold-start conditions. As a general-purpose unidirectional TVS, it fits anywhere a circuit needs protection against inductive kickback, lightning transients, or switching surges on a power rail up to roughly 5.8 V standoff.","metaTitle":"Vishay 1N6267A-E3/51 Zener TVS, 1.5kW Peak Pulse, DO-201AA","metaDescription":"Obsolete Vishay TransZorb Zener TVS, 1500W peak pulse, 10.5V clamping at 143A.
