Product details

Zener TVS for 77.8 V rail protection

Breakdown and clamping thresholds

Breakdown occurs at a minimum of 86.5 V, with the device clamping the line to 125 V maximum under the 8/20 µs pulse condition. The 4.8 A peak pulse current rating reflects the current that the 600 W rating sustains into a 125 V clamp — a useful sanity check when estimating the surge capacity into a given source impedance.

onsemi lists the P6KE91ARL as Obsolete. For a BOM line that requires this exact order code, sourcing runs through independent distribution or surplus channels.

Through-hole axial package, supplier device package Axial.

This covers cold-start outdoor cabinets and hot under-hood automotive environments without derating the peak pulse power — the 600 W rating is specified at 25°C; derate linearly above that per the datasheet curve.

Frequently asked questions

How can I order P6KE91ARL or check availability?

Because the part is obsolete, we source it through independent distribution and surplus channels. Submit an RFQ with your target quantity; we confirm current pricing and availability at quote time.

Is P6KE91ARL unidirectional or bidirectional?

Unidirectional — it has 1 unidirectional channel.

What is the difference between P6KE91ARL and P6KE91A?

The 'RL' suffix on P6KE91ARL indicates Tape & Reel packaging. The P6KE91A is the base part number and may be offered in bulk or other packaging formats. Electrical characteristics — breakdown voltage, power rating, package — are identical.
