A 12 V bus powered device with a 20 V abs-max input can tolerate this clamp, but a 5 V logic rail would need a secondary stage — the clamp voltage is too high for low-voltage ICs. Breakdown is specified at 11.4 V minimum, meaning the device starts conducting between 11.4 V and the clamp voltage. The 10.2 V standoff ensures no leakage at nominal 10 V or 12 V levels; the 1.5 kW rating covers most industrial transient profiles up to the 94 A peak. ## Active production — no lifecycle risk on this BOM line If dual-sourcing is required, other manufacturers offer pin-compatible 1.5KE12A variants with the same electrical ratings.","metaTitle":"1.5KE12A A0G TVS Diode, 1500W, 10.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE12A A0G unidirectional Zener TVS, 1500W peak pulse power, 10.2V standoff, 16.7V clamp.
