1.5 kW bidirectional transient suppressor
The 1.5KE200CA B0G: It clamps transients at 274 V maximum while the reverse standoff voltage is 171 V, meaning it sits across a 170 V rail and only conducts when a surge pushes beyond that threshold. Housed in a DO-201AA (DO-27) axial-lead package, it is a through-hole part suited for point-of-entry protection on DC power buses, telecom lines, or industrial control supplies where a single bidirectional device replaces two unidirectional diodes in series.
Clamping voltage and surge current
With a peak pulse current of 5.7 A at the 274 V clamping level, the 1.5KE200CA B0G absorbs a 1500 W surge without exceeding the junction temperature rating of -55°C to 175°C. The breakdown voltage range starts at 190 V minimum, so a 171 V nominal rail stays below the avalanche threshold during normal operation. The 1500 W rating is the peak pulse power for a 10/1000 µs exponential waveform — derate for shorter pulses or higher ambient temperature per the manufacturer's curve. The DO-201 package's axial leads conduct heat into the PCB traces, which matters when the device sees repetitive surges rather than a single event.
Sourced through authorized and independent distribution channels. Pricing and lead time are confirmed at RFQ against the BOM quantity. The bulk packaging means it ships loose in tubes or bags — store the reels dry if you cut tape, but the axial leads are not moisture-sensitive like a QFN.
