The DO-201AA / DO-27 axial-leaded package is a through-hole footprint common in industrial PSUs, telecom line cards, and motor-drive DC bus clamps where board space allows leaded insertion. ## Clamp voltage and peak current — what the ratings mean for your rail The breakdown voltage range starts at 37.1V minimum, guaranteeing the device turns on before the rail hits an unsafe level. That 53.9V is what the protected load sees during the surge — the downstream capacitor and rectifier must be rated above this clamp level to avoid secondary breakdown. Power derating above 25°C follows the standard exponential curve for axial-lead devices — the 1500W rating holds at 25°C and decreases linearly to zero at 150°C.","metaTitle":"YAGEO 1.5KE39CA/B Zener TVS, 1500W, 33.3V Standoff, DO-201","metaDescription":"YAGEO 1.5KE39CA/B bidirectional Zener TVS, 1500W peak pulse, 33.3V reverse standoff, 53.9V clamp at 28.2A.
