With a 17.1 V reverse standoff voltage, this part protects a nominal 12 V or 15 V rail — the TVS remains transparent below the standoff and only conducts when the transient exceeds the 19 V minimum breakdown threshold. ## Bidirectional clamp for AC or bipolar signal lines Single bidirectional channel means the TVS clamps symmetrically in both polarities — one device protects a signal pair or an AC-coupled line without needing two back-to-back unidirectional parts. The through-hole DO-201AA / DO-27 axial package suits point-to-point wiring on a terminal block or a PCB with drilled holes — the lead bend absorbs board flex and the body handles the thermal pulse of a 1500 W event without cracking the epoxy. ## Active production, general-purpose deployment Listed for General Purpose applications — no power-line protection rating, so it is intended for signal and low-power DC rail clamping rather than mains AC input protection.","metaTitle":"Vishay 1.5KE20CA-E3/73 TransZorb TVS, 1500W, 27.7V Clamp","metaDescription":"Vishay 1.5KE20CA-E3/73 bidirectional TVS diode, 1500W peak pulse power, 27.7V clamping.
