Product details

500 W surge clamp in an axial body

That 500 W rating means it can absorb a single surge of 10 A for a millisecond without failing — useful for clamping transients on a 27.4 V rail (the reverse standoff voltage). The 34.2 V minimum breakdown ensures the device starts conducting before the voltage climbs to the 49.9 V clamping ceiling.

Axial package and temperature range

Housed in an axial-lead B package (DO-13 style), the 1N6119A is a through-hole part that handles rework well — the leads are thick enough to survive a couple of removal cycles under a hot-air station without lifting the pad.

Microchip lists the 1N6119A as Active.

Frequently asked questions

How does the 1N6119A compare to the 1N6119?

The 1N6119A is the tighter-tolerance version of the 1N6119. Both share the same 500 W peak pulse power rating and axial package, but the 'A' suffix typically specifies a narrower breakdown voltage tolerance. For a design that needs a precise clamping threshold, the 1N6119A is the better choice.
