This means a 36.8 V supply bus sees the overvoltage clipped before it reaches downstream silicon. The 1500 W rating is for a 10/1000 µs exponential waveform — shorter pulses allow higher peak current; longer pulses require derating. The DO-201AA axial package handles the thermal pulse without secondary breakdown within the SOA. The through-hole axial package (DO-201AA / DO-27) is a standard footprint for board-level transient protection — easy to hand-replace in rework or field service.","metaTitle":"1.5KE43CA B0G TVS Diode, 1500W, 36.8V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE43CA B0G bidirectional Zener TVS, 1500W peak pulse, 36.8V standoff, 59.3V clamp.
