Product details

500 W peak pulse power, 42.6 V standoff — what it protects

This means it clamps a 42.6 V rail during a transient, absorbing up to 6.5 A of peak pulse current before the voltage rises to 77 V. The 500 W rating is the energy ceiling — beyond that the junction overheats.

Through-hole axial package and wide temperature range

Housed in a B, Axial through-hole package (supplier device package: Axial), the 1N6124A mounts into a standard PCB hole or terminal block — no reflow profile needed.

Active production — sourcing through distribution

Microchip lists the 1N6124A as Active. The base product number is 1N6124; the 'A' suffix indicates a tighter tolerance variant. For a BOM line, this means no second-source scramble — the part is orderable today.

Frequently asked questions

What is the power rating of 1N6124A?

The 1N6124A is rated for 500 W peak pulse power under a 10/1000 µs waveform. That is the maximum energy it can clamp in a single pulse before the junction temperature exceeds safe limits.

Is 1N6124A a Zener or TVS diode?

It is classified as a Zener type, specifically a bidirectional TVS diode. It clamps transients in both directions, with a reverse standoff of 42.6 V and breakdown at 53.2 V.
