Product details

Transient suppressor for harsh environments

Bidirectional clamping on a single axial part

One bidirectional channel protects both polarities of an AC signal or a bipolar data line without needing two diodes back-to-back. The 7.79V minimum breakdown gives a guard band above the 6.2V standoff, so a 5V rail with margin stays below the avalanche threshold during normal operation.

Microchip lists the 1N6104A as Active. The axial B, Axial package is a standard through-hole format that remains widely supported in legacy and new designs.

Frequently asked questions

Is the 1N6104A unidirectional or bidirectional?

Bidirectional — one channel protects both polarities. That makes it a direct fit for AC-coupled signal lines or bipolar supplies where a unidirectional part would need an external series diode.

What is the peak pulse power rating of the 1N6104A?

500W peak pulse power measured with a 10/1000 µs waveform. The 12.1V clamping voltage at 41.3A peak current defines the surge energy the part can absorb before the junction exceeds its thermal limit.
