1N2128A

Single Diodes Overview

The GeneSiC Semiconductor 1N2128A is a silicon standard recovery rectifier diode housed in a DO-5 stud mount package. It features a repetitive peak reverse voltage of 50 V and a continuous forward current rating of 60 A. The device operates within a junction temperature range of -55 °C to +150 °C, with a maximum thermal resistance from junction to case of 0.65 °C/W. Standard polarity configuration designates the stud as the cathode.

Single Diodes Feature Summary

• High surge capability for handling transient electrical loads
• Not sensitive to electrostatic discharge events
• Robust mechanical construction utilizing a threaded stud base

Single Diodes Applications

• General purpose power conversion circuits
• Industrial rectification systems
• Medium voltage power distribution equipment

Single Diodes Procurement Notes

Verify the specific part marking against the datasheet terminal configuration diagram to confirm polarity orientation. Ensure the mounting surface preparation meets the thermal interface requirements specified for the stud base. Confirm that the application environment remains within the stated operating temperature limits to maintain device reliability and performance specifications.

Single Diodes Selection Notes

Select this component when a high-current single-phase rectifier is required in a stud-mount form factor. The 50 V rating suits low-voltage AC-to-DC conversion applications. Consider the 60 A continuous current capacity and the rugged DO-5 package for designs needing robust mechanical attachment and efficient heat dissipation through the chassis.

Single Diodes Part Context

This component belongs to the 1N2128A through 1N2131AR series of silicon standard recovery diodes. The series covers voltage ratings from 50 V to 200 V while maintaining a consistent 60 A current rating across variants. All members share identical physical dimensions and thermal characteristics, differing primarily in their reverse voltage blocking capabilities.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-5 stud-mounted silicon rectifiers rated at 60 A and 50 V. Verify that substitute parts match the 0.65 °C/W thermal resistance and the 1/4-28 UNF thread specification for mechanical compatibility.
