It clamps a 12.1V reverse standoff rail to 22V maximum at a peak pulse current of 71A (10/1000µs waveform). ## What the clamping numbers mean on a 12V rail The 12.1V reverse standoff is the maximum DC voltage the diode will not conduct at — a 12V nominal battery bus or a 12V regulated supply sits below this threshold, so the TVS stays off in normal operation. The 1500W peak pulse rating (10/1000µs) defines the energy the part can absorb in a single transient — a 24V automotive load-dump pulse or an ISO 7637-2 test pulse 5a at this energy level will be clamped without the diode failing short.","metaTitle":"1.5KE15H TVS Diode, 1500W, 12.1V Standoff, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE15H Zener TVS, 1500W peak pulse, 12.1V reverse standoff, AEC-Q101 automotive grade.
