The 1500W peak pulse rating is derated linearly above 25°C; at 175°C the device still handles roughly 600W, enough for most ISO 7637-2 pulse 5a load-dump events on a 12V system. ## Bidirectional clamp for a single-rail architecture A single bidirectional channel protects a 12V bus from both positive and negative transients without needing a series diode or a second device. The 82.4A peak pulse current at the 10/1000µs waveform defines the surge capability: a 1500W TVS at 18.2V clamp delivers 82.4A, so the upstream fuse or circuit breaker must open before the TVS exceeds its non-repetitive peak current rating. The axial DO-201AA (DO-27) body requires a 1.3mm diameter through-hole on the PCB; the copper pad area on both sides of the board sets the thermal impedance for repetitive pulse trains.","metaTitle":"1.5KE13CAHE3_A/D Vishay TVS, 1500W, 11.1V, AEC-Q101","metaDescription":"Vishay 1.5KE13CAHE3_A/D bidirectional TVS diode, 1500W peak pulse, 11.1V standoff, AEC-Q101 qualified.
