Its 102 V reverse standoff voltage means it sits across a nominal 100 V bus without conducting leakage, then clamps transients at 165 V maximum. ## Breakdown and clamping window Minimum breakdown voltage is 114 V, so the device starts conducting between 114 V and the 165 V clamp ceiling. The 9.1 A peak pulse current rating (10/1000 µs waveform) confirms it can absorb the surge energy from a load-dump or inductive kickback event on a 100 V nominal bus. ## Package and sourcing posture Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE120CAHE3_A/C is a through-hole part suited for point-of-use transient suppression on power input stages. The base product number is 1.5KE120, and the HE3 suffix denotes the AEC-Q101 automotive grade. Vishay lists this part as Active in production.","metaTitle":"1.5KE120CAHE3_A/C Vishay TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5KE120CAHE3_A/C 1500W bidirectional TVS, AEC-Q101 qualified, 102V standoff, DO-201AA axial.
