Part of the Automotive, AEC-Q101, TransZorb® series — AEC-Q101 certification means it meets the automotive-grade stress and reliability tests (temperature cycling, high-temperature reverse bias, and ESD) required for under-hood or cabin electronics. ## Package and board integration Supplied in a DO-201AA / DO-27 axial-lead through-hole package. The bulk packaging (not tape-and-reel) means it is suited for hand-insertion or low-volume assembly rather than automated pick-and-place. The axial leads require through-hole pads on the PCB; the body diameter and lead spacing are standard for this DO-201 footprint.","metaTitle":"1.5KE12CAHE3/51 Vishay TVS, 1.5kW, Bidirectional, DO-201","metaDescription":"Obsolete 1.5KE12CAHE3/51 TVS diode, 1.5kW peak pulse, 10.2V standoff, AEC-Q101.
