1N2129RA

Single Diodes Overview

The 1N2129RA is a standard recovery rectifier manufactured by Microchip Technology. It features a single configuration with a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current rating of 60 A. The device exhibits a maximum forward voltage drop of 1.3 V at rated current and supports a non-repetitive peak forward surge current of 900 A. It operates within a junction temperature range of -65 °C to +190 °C and utilizes a stud mount installation style in a DO-5 package.

Single Diodes Feature Summary

• Standard recovery rectifier design for general-purpose power conversion applications
• Robust thermal performance supporting high junction temperatures up to 190 °C
• High surge current capability for handling transient load conditions

Single Diodes Applications

• Industrial power supply circuits
• Battery charging systems
• DC-to-AC inversion stages

Single Diodes Procurement Notes

Verify the manufacturer designation carefully, as the component identifier 1N2129RA is historically associated with Vishay Semiconductors. Confirm that the specific lot or datasheet provided by Microchip Technology explicitly covers this part number before procurement. Ensure the ordering documentation matches the required electrical specifications and package type to avoid integration errors.

Single Diodes Selection Notes

Select this component when a high-current single-phase rectifier with a 100 V blocking voltage is required. The DO-5 stud mount package facilitates direct mounting to heatsinks for efficient thermal management. Verify that the system's thermal design can accommodate the specified operating temperature range and that the 60 A current rating meets the continuous load requirements.

Single Diodes Part Context

This component belongs to the family of standard recovery rectifiers designed for medium-power applications. It provides a balance of switching speed and forward conduction efficiency suitable for low-frequency power electronics. The DO-5 package offers a compact footprint for stud-mounted implementations in industrial enclosures.

Single Diodes Replacement Considerations

Cross-reference with other 1N2129 variants from different manufacturers to ensure pinout and mechanical compatibility. Verify that substitute parts meet or exceed the 60 A current and 100 V voltage ratings.
