No pin-compatible direct replacement from Vishay is documented. ## What the key ratings mean for the BOM The 175 V reverse standoff voltage means the device does not conduct at normal line levels below that threshold — it sits transparently on the rail until a surge pushes the voltage past the 198 V minimum breakdown point. The DO-201AA axial-lead package is a through-hole form factor suited for point-to-point wiring or PCB mounting with standard lead spacing. ## Where this TVS fits in the circuit Classified as a General Purpose transient suppressor, the 1.5KE220C-/54 is typically placed across a DC bus or signal line to shunt overvoltage events to ground. Because power line protection is listed as 'No', this part is not designed for continuous AC mains clamping; it is intended for secondary-side or equipment-level surge suppression where the energy is discrete and infrequent.","metaTitle":"1.5KE220C-E3/54 TVS Diode, 1500W, 175V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE220C-E3/54 bidirectional TVS, 1500W peak pulse, 175V standoff, DO-201AA.
