Its 102 V reverse standoff voltage and 114 V minimum breakdown voltage put it squarely on 72 V to 96 V nominal DC bus rails found in electric vehicle battery packs, industrial servo drives, and high-voltage telecom rectifiers. ## Clamping voltage and pulse current — what the numbers decide At the 9.5 A peak pulse current (10/1000 µs waveform), the maximum clamping voltage is 165 V. That is the ceiling the protected circuit sees — a downstream 200 V-rated MOSFET or 175 V DC-link capacitor has margin. The 102 V standoff means the diode stays off during normal bus ripple up to that level, so no leakage current penalty under steady-state operation. AEC-Q101 qualification adds the reliability screening — 1000-hour high-temperature reverse bias and temperature cycling — that automotive PPAP submissions require. ## Through-hole DO-201 — board-fit and sourcing note The DO-201AA / DO-27 axial package is a standard 0.052-inch diameter lead, 0.375-inch body length. The lead bend radius and hole diameter for the PCB footprint follow the JEDEC DO-201 outline — no custom tooling needed.","metaTitle":"1.5KE120CAH TVS Diode, 1500W, Bidirectional, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE120CAH bidirectional TVS diode, 1500W peak pulse power, 102V standoff, AEC-Q101 qualified.
