With a 10.2 V reverse standoff voltage and a 16.7 V clamping point at 94 A peak pulse current (10/1000 µs waveform), it protects a 12 V DC rail from transients like load dump or inductive kickback — the clamp triggers before the downstream regulator's abs-max is reached. The 94 A peak pulse current rating means this diode can sink a short, high-energy surge without failing short — that is the number that matters for fuse coordination and trace width on the PCB. ## Package and field-swap reality Housed in a DO-201AA (DO-27) axial-lead package, it is a through-hole part — the kind you can swap on site with a soldering iron and a desoldering pump. No hot-air station needed, no reflow profile to worry about. The cathode band is clearly marked on the body, so orientation is one look. ## Sourcing and compliance The 1.5KE series is a standard JEDEC DO-201 footprint, so parametric equivalents from other manufacturers exist, but pin-compatibility is not formally documented.","metaTitle":"1.5KE12A R0G TVS Diode, 1.5kW, 10.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE12A R0G Zener TVS, 1500W peak pulse, 10.2V reverse standoff, 16.7V clamp.
