The 34.8 V standoff means it protects 36 V nominal rails (common in 24 V automotive systems with load-dump transients) without conducting during normal operation. The 61.9 V clamp keeps the surge voltage below the typical 70 V abs-max of downstream DC-DC converters. Housed in a DO-201AA (DO-27) axial-lead through-hole package. The lead spacing and body diameter match the standard 1.5KE footprint — no board layout change versus other 1.5KE-series parts. The bidirectional marking means no orientation concern during insertion.","metaTitle":"Vishay 1.5KE43CHE3/73 TVS Diode, 1500W, Bidirectional","metaDescription":"Obsolete Vishay 1.5KE43CHE3/73 automotive TVS diode, 1500W peak pulse, 34.8V standoff, bidirectional, AEC-Q101.
