Product details

High-temperature deployment and the -55 to 175 °C window

The 5KP15A-HRA: Rated for -55 to 175 °C ambient, this part covers the full military-to-industrial temperature band — the upper limit makes it viable for engine-adjacent or enclosed-panel locations where ambient can run hot without forced cooling.

P600 axial package and through-hole mounting

The P600 axial package mounts perpendicular to the board in a hole pattern — the lead spacing and body diameter are fixed by the package standard, so board layout follows the datasheet footprint rather than a flexible pinout. Tape-and-reel packaging is standard for high-volume assembly; a through-hole lead dress absorbs mechanical shock without a compliant-lead concern.

Frequently asked questions

Where can I source the 5KP15A-HRA and what is the typical lead time?

Quoted to order through independent distribution against your BOM quantity.

Is there a pin-compatible alternative in the 5KP-HRA series?

The 5KP-HRA series shares the P600 axial footprint, but standoff and clamping ratings are fixed by the part number — the 5KP15A-HRA clamps at 24.4 V for a 15 V standoff. Confirm the exact voltage window your protection circuit requires before cross-shopping within the series.
