Product details

Active production, axial TVS for 13.7 V rails

Its 13.7 V reverse standoff voltage makes it a direct fit for protecting 12 V nominal DC rails — the clamping voltage hits 26.36 V at the full 18.91 A peak pulse current. The through-hole axial package (B, Axial) is a legacy footprint still widely used in industrial and military power supplies, motor drives, and field I/O modules where board space is not the constraint.

Junction temperature and pulse handling

The 500 W peak pulse power is specified with a 10/1000 µs waveform — for shorter pulses the peak power capability rises, but the 18.91 A clamp current is the hard limit for that pulse shape. Power line protection is not supported, so this part is intended for signal or low-power DC rail clamping, not AC mains.

Sourcing and production status

Listed as Active by Microchip, so no last-time-buy clock is ticking. The through-hole axial package is a standard, widely stocked form factor.

Frequently asked questions

What is the difference between 1N6112 and 1N6111?

The 1N6112 has a 13.7 V reverse standoff voltage, while the 1N6111 is a lower-voltage variant in the same family. Both share the same 500 W peak pulse power rating and axial package — the standoff voltage is the selection axis.
