The 114 V minimum breakdown means it starts conducting just above the normal operating voltage, and the 165 V maximum clamp at 9.1 A peak pulse current (10/1000 µs waveform) keeps the spike off the downstream silicon. That 1500 W rating is the peak pulse power for a 1 ms pulse — derate for longer events or higher ambient temps per the datasheet curve. Through-hole DO-201AA (DO-27) axial package — easy to hand-replace on a board with a soldering iron and a pair of cutters. No hot-air station needed; the leads are long enough to dress through the board and trim after soldering. Bidirectional single-channel means one part handles both polarities, saving a diode on a bipolar rail. ## Temp range and where it sits in the circuit The 102 V reverse standoff is the DC rail voltage it can sit across without leaking appreciably; a 100 V bus or a 48 V telecom rail with transients is the natural home. Note the 'Power Line Protection: No' flag — this is a data-line / low-impedance bus protector, not a primary AC mains suppressor. ## Active production — sourcing posture This is a standard catalog TVS, widely second-sourced in the 1.5KE family.","metaTitle":"1.5KE120CA-E3/73 Vishay TVS, 1500W, 102V Standoff, DO-201","metaDescription":"Active Vishay 1.5KE120CA-E3/73 bidirectional TVS diode, 1500W peak pulse, 102V standoff, 165V clamp.
