The reverse standoff of 20.5 V typ means the protection node sits below the clamping threshold during normal operation, drawing only leakage — when a surge exceeds standoff, the breakdown activates at a minimum 22.8 V and the diode enters the low-impedance clamp state. ## Sourcing an obsolete automotive TVS The DO-201AA (DO-27) package and the 1.5KE device type are shared across a range of standoff voltages in the 1N628x family, so a same-footprint alternative at the correct standoff and clamping rating may exist within the legacy catalogue, but any cross-reference must be confirmed against the specific voltage window of the protected node. Sourcing is through independent distribution — lot traceability, date-of-manufacture and genuine-part verification fall on the buyer to specify at RFQ, especially for automotive-qualified parts where the OEM auditor will ask for traceability back to the wafer fabrication site on the PPAP documentation.","metaTitle":"Vishay 1N6280AHE3/51 Zener TVS Diode, 20.5V standoff","metaDescription":"Vishay 1N6280AHE3/51 Automotive AEC-Q101 TransZorb TVS diode, 1500W peak pulse, 33.2V clamp.
