Product details

1.5kW TransZorb® TVS — 408 V standoff, 658 V clamp

The 1.5KE480A-E3/51: The 1500 W rating means it absorbs a 10/1000 µs surge up to that power level without failing — a common benchmark for secondary surge protection in industrial and telecom power supplies.

Last-time-buy — sourcing the 1.5KE480A-E3/51 now

Vishay lists the 1.5KE480A-/51 as Last Buy — the manufacturer has announced end-of-life and is accepting final orders within a defined window.

Through-hole DO-201AA axial — board-fit and temperature range

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE480A-/51 mounts through-hole and is supplied in bulk. The operating junction temperature range spans -55°C to +175°C. The wide temperature grade suits environments where the TVS sees self-heating from repetitive surges — the 175°C TJ max provides margin above the 150°C typical for many industrial TVS parts.
