Product details

28V standoff, 1500W pulse — 24V rail clamp

Its 28V reverse standoff voltage sits comfortably above a nominal 24V supply, so the diode stays off during normal operation but begins to avalanche at 31.4V minimum breakdown. Under a 10/1000µs surge waveform it clamps at 45.7V maximum while conducting 33A peak pulse current, and the device is rated to absorb 1500W of peak pulse power. The DO-13 through-hole package is a metal-can hermetic style that handles the thermal pulse of a 1.5kW event without cracking the die attach.

Junction temperature range and mounting

This makes the 1N6051A/TR suitable for under-hood automotive, avionics, or downhole instrumentation where ambient temperatures push junction temperatures above 150°C.

Frequently asked questions

Can 1N6051A/TR be used for 24V circuit protection?

Yes. The reverse standoff voltage is 28V, which is 4V above a nominal 24V rail. That gives enough margin to avoid false triggering during normal operation while still clamping before the rail sees damaging overvoltage.

Is 1N6051A/TR bidirectional?

Yes, it has one bidirectional channel. It clamps both positive and negative transients with a single device, so you do not need to worry about polarity when placing it on the board.

What package does 1N6051A/TR come in?

It is supplied in a DO-13 through-hole package, with the TR suffix indicating Tape & Reel packaging for automated handling.
