It clamps transients on a 33.3 V nominal rail — the reverse standoff voltage — and starts conducting at 37.1 V minimum breakdown. At the full 29 A peak pulse current (10/1000 µs waveform,), the clamping voltage reaches 53.9 V maximum. That 53.9 V ceiling is what the downstream silicon sees; if your 33 V bus has a 60 V abs-max FET on it, this TVS holds the gate voltage inside the safe operating area. ## Through-hole axial package — board-fit note Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE39A B0G is a through-hole part intended for point-to-point wiring or PCB mounting with 0.040-inch diameter leads. The DO-201 footprint is standard across the 1.5KE series, so a single board layout accepts the whole voltage range. The bulk packaging suits hand-insertion or low-volume assembly; no tape-and-reel option is listed on this order code. ## Sourcing and procurement Taiwan Semiconductor Corporation lists the 1.5KE39A B0G as an active product.","metaTitle":"1.5KE39A B0G TVS Diode, 1500W, 33.3V Standoff, DO-201","metaDescription":"1.5KE39A B0G Zener TVS diode, 1500W peak pulse power, 33.3V standoff, 53.9V clamp.
