Breakdown occurs at 37.1 V minimum — the zener threshold where conduction starts. The unidirectional channel clips only one polarity, so the cathode band must face the rail being protected; reverse insertion leaves the circuit exposed. ## Package and board integration The DO-201 supplier device package matches the JEDEC outline; leads are tin-plated for solderability. Operating temperature range covers -55°C to 150°C junction — wide enough for outdoor telecom cabinets, industrial motor drives, and under-hood automotive modules where ambient heat plus self-heating from repeated surges must stay within the junction limit.","metaTitle":"YAGEO 1.5KE39A/B Zener TVS, 1500W, DO-201, Active","metaDescription":"YAGEO 1.5KE39A/B Zener TVS diode, 1500W peak pulse power, 33.3V standoff, 53.9V clamp.
