1N3266

Single Diodes Overview

The Microchip Technology 1N3266R is a standard recovery rectifier diode designed for high-current applications. It features a maximum DC reverse voltage (Vr) of 350 V and an average forward rectified current (Io) of 275 A. The device exhibits a maximum forward voltage (Vf) of 1.3 V at 300 A and a reverse leakage current of 75 µA at 350 V. Operating within a junction temperature range of -65°C to 190°C, it utilizes a DO-205AB (DO-9) stud mount package.

Single Diodes Procurement Notes

Verify the specific suffix requirements for your assembly process, as the base part number may have variants such as R or MS. Confirm RoHS compliance status prior to ordering, as this component family may not meet all environmental directives. Ensure the stud mount interface matches your heatsink design specifications before finalizing procurement.

Single Diodes Selection Notes

Select this component when designs require robust high-current rectification in compact stud-mount packages. Evaluate the thermal management requirements carefully due to the significant heat generation at full load. Compare the 350 V reverse voltage rating against peak inverse voltage spikes in the target circuit to ensure adequate safety margins during operation.

Single Diodes Part Context

This device belongs to the 1N3266 series of high-power rectifiers manufactured by Microchip Technology. It serves as a discrete semiconductor solution for power electronics, distinct from integrated circuits like the PIC32 MCUs also produced by the manufacturer. The DO-205AB package provides a reliable mechanical connection for high-amperage applications.

Single Diodes Replacement Considerations

Consult official substitution guides for equivalent high-current stud-mount diodes. Verify that any replacement maintains the 275 A current rating and 350 V reverse voltage specification to ensure circuit compatibility.
