Transient suppressor for high-energy environments
The 1N6072A is a Zener diode from Microchip Technology designed for general-purpose circuit protection, clamping transients in a single bidirectional channel. Its 1500W peak pulse power rating (10/1000µs waveform) handles substantial surge energy, making it suitable for power supply inputs, industrial controls, and telecom equipment where repetitive or one-shot overvoltage events occur. The device operates across -55°C to 175°C junction temperature, so it can be placed in hot environments like engine bays or near power stages without derating the surge capability prematurely.
Clamping voltage and breakdown margin
With a reverse standoff voltage of 185V and a minimum breakdown voltage of 209V, the 1N6072A begins conducting just above the nominal rail, leaving a 24V margin before avalanche. The maximum clamping voltage at 4.6A peak pulse current is 328V, which defines the voltage the downstream circuitry must survive during a surge event.
Active production — no obsolescence concern
Microchip lists the 1N6072A as Active in production.
Through-hole DO-13 package for retrofit and new builds
The DO-13 (also known as DO-202AA) through-hole package suits point-to-point wiring, socketed applications, or PCB layouts where a robust leaded device is preferred over surface-mount.
