The clamping voltage at that peak current is 328 V, which sets the upper limit the downstream circuitry must survive. It is a unidirectional suppressor — one channel, biased for DC lines where the signal stays above ground. ## Automotive qualification and temperature envelope Graded Automotive and qualified to AEC-Q101, the 1.5KE220AH is built for the reliability demands of vehicle electronics — engine control units, battery management systems, and auxiliary loads that see under-hood temperature swings. It handles the thermal dissipation of a 1500 W pulse without a heatsink — the axial leads conduct the heat into the PCB copper. ## Sourcing and compliance Compliance documentation — RoHS, REACH, and AEC-Q101 qualification data — is maintained by the manufacturer and can be provided with the shipment.","metaTitle":"1.5KE220AH TVS Diode, 1500W, 185V Standoff, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE220AH Zener TVS, 1500W peak pulse, 185V reverse standoff, 328V clamping.
