1500 W axial TVS for general-purpose rail protection
The 1.5KE51A B0G is a 1500 W peak-pulse-power Zener TVS diode from Taiwan Semiconductor Corporation's 1.5KE series, housed in a DO-201AA (DO-27) axial-lead package for through-hole mounting. 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.
