Product details

1500W bidirectional Zener TVS in an axial leaded package

The 1N6149A is a single bidirectional Zener TVS diode from Microchip Technology, rated for 1500W peak pulse power at 10/1000µs. It clamps at 27.7V maximum with a 15.2V reverse standoff, handling 54.2A peak pulse current. The axial package makes it a straightforward through-hole install for board-level or point-of-entry surge protection.

Microchip lists the 1N6149A as Active.

Rated for -55°C to 175°C junction temperature, the 1N6149A suits harsh environments where commercial-grade TVS diodes would derate or fail — engine bay electronics, downhole instrumentation, avionics, and outdoor telecom enclosures.

Frequently asked questions

Is 1N6149A bidirectional or unidirectional?

It is a single bidirectional channel. It clamps both polarities, so it works on AC lines or bipolar supplies without pairing two parts.

What is the peak pulse power of 1N6149A?

1500W peak pulse power at 10/1000µs waveform. That rating defines its surge-handling capacity for a given pulse duration.
