Breakdown voltage min is 198 V, so the device starts conducting between 198 V and the clamp limit. ## DO-201AA axial — board-fit note Through-hole DO-201AA (DO-27) axial package — the leads are formed for through-hole insertion; the body is 5.3 mm diameter typical. No surface-mount variant exists in this order code.","metaTitle":"1.5KE220CHE3/73 TVS Diode, 1500W, 175V, DO-201AA, Obsolete","metaDescription":"Vishay 1.5KE220CHE3/73 Zener TVS, 1500W peak pulse, 175V reverse standoff, AEC-Q101.
