The minimum breakdown voltage is 40.9V, so the protection window opens cleanly above the nominal rail voltage without nuisance triggering on normal transients. A single bidirectional channel handles both positive and negative surges, which simplifies layout for AC-coupled lines or bipolar supplies where polarity is not fixed. The 1500W rating at 10/1000µs is the standard automotive surge waveform for load-dump and inductive kickback. ## DO-201AA axial package and temperature range The DO-201AA (DO-27) axial through-hole package is a standard TVS footprint that mates with existing PCB layouts and supports wave-solder or hand-solder assembly. Tape and Reel packaging is specified for automated pick-and-place in volume production. The AEC-Q101 qualification includes temperature cycling and high-temperature reverse bias stress testing.","metaTitle":"Vishay 1.5KE43CAHE3_A/C TVS, AEC-Q101, 1500W, 36.8V","metaDescription":"Vishay 1.5KE43CAHE3_A/C TransZorb TVS diode, AEC-Q101 qualified, 1500W peak pulse, 36.8V standoff, DO-201AA axial.
