Breakdown occurs at 48.5V minimum, and the clamping voltage is held to 70.1V at the peak pulse current — the load sees no more than 70.1V during the surge event. ## Axial through-hole package and temperature range Housed in a DO-201AA / DO-27 axial-lead package, the 1.5KE51A/B mounts through-hole on a PCB or terminal strip — the axial body and 0.040-inch leads suit point-to-point wiring or board-level transient protection where the surge current path must be short and low-inductance. Junction temperature range is -55°C to 150°C, covering military and industrial ambient conditions — the derating curve above 25°C reduces the peak pulse power linearly, so at 125°C the effective rating is roughly 50% of the 1500W figure.","metaTitle":"YAGEO 1.5KE51A/B Zener TVS, 1500W, 43.6V Standoff","metaDescription":"YAGEO 1.5KE51A/B Zener TVS diode, 1500W peak pulse power, 43.6V reverse standoff, DO-201 axial.
