The 11.4 V minimum breakdown voltage is the turn-on threshold at 25 °C junction temp — the 1.64× ratio between breakdown and clamping ceiling is typical for this class and reflects the diode's dynamic resistance under surge conditions. ## Last-Buy lifecycle — what that means for procurement Vishay General Semiconductor lists this part as Last Buy — no new production after the window closes, no official successor cited on the record.","metaTitle":"Vishay 1N6273A-E3/51 Zener TVS Diode, 10.2V standoff","metaDescription":"Vishay 1N6273A-E3/51 TransZorb® Zener TVS, 1500W peak pulse, 10.2V standoff / 16.7V clamp.
