That makes it a fit for under-hood or chassis-mounted ECU power inputs where load-dump, alternator surge, and inductive kickback are the daily threat. ## Bidirectional, single-die — one part covers both polarities A single bidirectional channel protects against positive and negative transients without needing two series diodes. The DO-201AA axial package is a through-hole leaded form — it handles the thermal cycling of power-stage clamping better than a surface-mount equivalent in the same power class.","metaTitle":"Vishay 1.5KE220CAHE3_A/D TVS, 1500W, 185V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE220CAHE3_A/D bidirectional TVS diode, 1500W peak pulse, 185V standoff, AEC-Q101 qualified, DO-201AA axial.
