Product details

1.5kW peak pulse, 414V clamp — the rail protection number that matters

The 1.5KE300A-T: At the 414 V clamping voltage it conducts 5 A of peak pulse current (10/1000 µs waveform), absorbing 1500 W of peak pulse power.

Obsolete — no official successor on record

Diodes Incorporated lists the 1.5KE300A-T as obsolete. No official successor part number is provided by the manufacturer.

DO-201 axial body, -55 to 175 °C junction range

The part comes in a DO-201AA (DO-27) axial-lead package, also designated as supplier device package DO-201. Through-hole mounting with the barrel body — the lead spacing matches standard 0.3-inch pitch on a prototype board or terminal block.
