Product details

Active production — no end-of-life risk for this BOM line

The 1.5KE47A A0G: For a procurement desk qualifying a transient suppression diode into a 40.2 V rail, this active status removes the single-source risk that comes with NRND or EOL parts — no need to qualify an alternate preemptively.

1500 W peak pulse — what the 10/1000 µs rating means for your rail

The 40.2 V reverse standoff voltage means the diode draws negligible leakage below that rail level, while the 44.7 V minimum breakdown ensures it triggers before the protected circuit's absolute maximum rating is exceeded. With no power line protection rating, this unidirectional TVS is intended for DC signal or low-voltage supply rails, not AC mains transient suppression — the 10/1000 µs pulse shape matches IEC 61000-4-5 surge testing for equipment-level transients.

DO-201 axial package — through-hole footprint and temperature range

Housed in a DO-201AA / DO-27 axial leaded package, the 1.5KE47A A0G mounts through-hole — a common footprint for replacement in existing power supply and I/O protection designs where surface-mount TVS arrays are not an option.
