The 102 V reverse standoff means it sits across a 100 V nominal rail without conducting leakage; the 114 V minimum breakdown is where it starts clamping, and the 165 V maximum clamp at 9.1 A peak pulse (10/1000 µs waveform) defines the voltage the downstream circuitry sees during a surge. ## Sourcing an obsolete protection diode Available through independent surplus and broker channels.","metaTitle":"1.5KE120A-T Diodes Inc TVS, 1500W, DO-201, Obsolete","metaDescription":"1.5KE120A-T Diodes Incorporated 1500W unidirectional TVS, 102V standoff, 165V clamp, DO-201 axial.
