408 V standoff, 1500 W peak — what the ratings mean
The 1.5KE480: The reverse standoff voltage of 408 V is the maximum continuous DC voltage the diode blocks without conducting — match this to your nominal rail voltage, not the peak. When a surge hits, the diode breaks down at a minimum of 432 V and clamps the transient to 690.9 V maximum while shunting 2.3 A of peak pulse current (, 10/1000 µs waveform). The 1.5 kW rating is a peak figure, not continuous; the device is not intended for power-line protection.
DO-201 axial — board-fit and temperature envelope
Through-hole mounting in a DO-201AA / DO-27 axial package, with the supplier device package designated DO-201. The axial leads suit point-to-point wiring or through-hole PCB layouts — the body is the same diameter as a standard 1N62xx series, so existing board footprints for similar 1500 W TVS diodes are likely compatible. Junction temperature range spans -55°C to 175°C, covering industrial and outdoor equipment where the ambient may hit 85°C and the diode self-heats during a surge. The wide Tj margin means derating is only necessary above 25°C ambient per the datasheet curve.
Obsolete — sourcing reality and what to expect
For existing BOM lines or repair stock, the 1.5KE480 is available through independent surplus and broker channels. Sourced to order against an RFQ — date codes and lot traceability confirmed at quote time. No stock-holding claim; availability verified per request.
