With a 43.6 V reverse standoff voltage and a clamping ceiling of 70.1 V at 22 A peak pulse current (10/1000 µs waveform), this part protects 48 V nominal rails from transients — the clamp voltage sits below the typical 80 V abs-max of downstream DC-DC converters on that bus. ## Breakdown, clamp, and thermal envelope The single unidirectional channel clamps positive transients; for bidirectional protection on AC lines or bipolar supplies, two devices are wired back-to-back. ## Active lifecycle and procurement Sourced through independent distribution; pricing and lead time are confirmed at RFQ against the required quantity.","metaTitle":"1.5KE51A B0G TVS Diode, 1500W, DO-201, Taiwan Semi","metaDescription":"1.5KE51A B0G Zener TVS diode, 1500W peak pulse power, 43.6V standoff, 70.1V clamp.
