Clamping is specified at 64.8 V maximum at 24 A peak pulse current, which sets the voltage the downstream circuitry must survive during a surge event. The 1500 W rating means it can absorb a single 10/1000 µs pulse of that energy without failing short — useful for secondary protection on DC power inputs, relay coils, or signal lines in industrial and telecom gear. ## DO-201 axial — through-hole mounting and temperature range The wide temperature window means the leakage current and clamping voltage shift predictably across the band — derate the peak pulse power above 25 °C per the datasheet curve. ## Active production — sourcing posture The part is a single-channel unidirectional device; for bidirectional or higher-power requirements, the 1.5KE series includes other standoff voltage options in the same DO-201 footprint.","metaTitle":"1.5KE47A B0G TVS Diode, 1500W, 40.2V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE47A B0G unidirectional TVS, 1500W peak pulse power, 40.2V standoff, 64.8V clamp.
