Product details

500W bidirectional Zener TVS in a through-hole axial package

It clamps transients at 151.3V max with a reverse standoff of 86.6V, making it suitable for protecting 86V DC rails or signal lines from surges up to 3.3A peak pulse current. The single bidirectional channel means one device protects both positive and negative overvoltage events on a line, saving board space compared to two unidirectional diodes back-to-back.

Minimum breakdown voltage is 104.5V, so the diode begins conducting at that threshold. For a 86.6V nominal rail, this leaves a 17.9V margin above the standoff before clamping, which is typical for a Zener-based TVS. The wide range means the breakdown voltage shifts less than 10% across temperature, but derate the peak pulse power above 25°C per the datasheet curve.

Active production – sourcing through distribution

The through-hole B Axial package is a leaded form factor compatible with wave soldering and hand rework. No moisture sensitivity level (MSL) concern — axial diodes are not moisture-sensitive.

Frequently asked questions

Is 1N6131A a bidirectional or unidirectional TVS diode?

It is a single-channel bidirectional Zener TVS. It clamps both positive and negative transients on the same line, so you do not need two unidirectional devices in anti-series.

What is the peak pulse power rating of 1N6131A?

500W peak pulse power per the 10/1000µs waveform. Derate linearly above 25°C junction temperature; at 175°C the rating drops to near zero.
