For BOM lines that still require this exact order code, supply is through independent surplus and broker channels. ## Key protection ratings and what they mean The bidirectional single-channel design clamps both polarities with one device. Reverse standoff voltage is 41.3 V typical; the device starts conducting at breakdown (minimum 45.9 V) and clamps the transient to a maximum of 73.5 V at 20.4 A peak pulse current. That clamping voltage is what the downstream circuitry must survive. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead package — a through-hole form factor that suits point-to-point wiring or PCB mounting with the leads formed to the hole pitch. The 1.5KE package code is the supplier device designation.","metaTitle":"1.5KE51C-E3/54 Vishay TransZorb TVS, 1500W Bidirectional","metaDescription":"Obsolete Vishay 1.5KE51C-E3/54 TransZorb bidirectional TVS diode, 1500W peak pulse, 41.3V standoff, DO-201AA axial.
