Product details

Rated for 1500W peak pulse power (10/1000µs waveform), with a reverse standoff voltage of 8.55V and a maximum clamping voltage of 14.5V at 103A peak pulse current — suitable for protecting 8.55V DC rails from transient overvoltage events.

Buyers should plan for a last-time buy or identify a drop-in replacement from the same 1.5KE family.

Through-hole axial package — confirm the lead spacing and hole diameter on your PCB before committing; the axial form factor is straightforward to hand-solder or wave-solder.

Frequently asked questions

How can I order the 1.5KE10ARL4 or check stock?

The 1.5KE10ARL4 is obsolete per onsemi. We can source remaining inventory from our supply network — submit an RFQ with your target quantity and we will confirm availability and pricing at quote time.

What is the replacement for the 1.5KE10ARL4?

The base product number is 1.5KE. A direct functional replacement would be another 1.5KE-series Zener TVS with the same 8.55V standoff and 1500W rating, such as the 1.5KE10A (note the suffix difference — confirm the breakdown voltage and clamping specs match your design). onsemi does not list a specific successor; cross-reference against the 1.5KE10A datasheet for pin-compatible fit.
