1N1126RA

Single Diodes Overview

The Microchip Technology 1N1126RA is a standard recovery silicon power rectifier designed for high-reliability applications. It features a single-phase configuration housed in the DO-203AA (DO-4) stud mount package. The device supports a maximum repetitive peak reverse voltage of 400V and an average forward rectified current of 3.3A. It withstands a maximum surge current of 25A and exhibits a low reverse leakage current of 5µA at rated voltage. The component operates within a junction temperature range of -65°C to +150°C, ensuring robust performance in demanding thermal environments.

Single Diodes Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides valid traceability records for high-reliability components. Confirm RoHS compliance status as indicated in the latest datasheet revision before finalizing orders.

Single Diodes Selection Notes

Select this component when a rugged, stud-mount rectifier with 400V blocking capability is required. The 3.3A continuous current rating suits moderate-power applications where thermal management via chassis mounting is feasible. Consider the standard recovery speed for non-switching or low-frequency AC-to-DC conversion tasks.

Single Diodes Part Context

This part belongs to the legacy 1N series of power rectifiers, now manufactured under the Microchip Technology portfolio following acquisitions. The DO-203AA package is a traditional axial leaded stud-mount style, distinct from modern surface-mount technologies. It serves as a direct replacement for older military-grade specifications in industrial equipment.

Single Diodes Replacement Considerations

Direct substitutes include the 1N1126AR variant, which shares identical electrical ratings but may differ in packaging quantity or specific manufacturing lot details. Verify pinout compatibility and thermal resistance values when cross-referencing with other manufacturers' equivalents.
