1N2794

Single Diodes Overview

The Microchip Technology 1N2794 is a silicon power rectifier designed for industrial control applications. It features a stud mount configuration within the DO-5 (DO-203AB) package, facilitating robust thermal management and secure mechanical attachment to heat sinks. The device supports an average rectified current of 5A and withstands a repetitive peak reverse voltage of 100V. It operates across a wide junction temperature range from -65°C to +200°C, ensuring reliability in demanding environments. Reverse leakage current is specified at 10 µA when tested at 100V.

Single Diodes Procurement Notes

Verify the manufacturer origin carefully, as the 1N2794 designation has been produced by multiple entities including Microsemi and New Jersey Semi-Conductor. Confirm that the specific unit received matches the Microchip Technology part number and includes the correct DO-5 stud mount package. Request official datasheets to validate electrical parameters such as forward voltage drop and surge current ratings before integration into critical designs.

Single Diodes Selection Notes

Select this component when a rugged, stud-mounted rectifier is required for high-current industrial applications. The 5A continuous rating and 100V blocking voltage suit standard low-voltage AC-to-DC conversion tasks. Ensure the mounting surface allows for proper torque application to maintain thermal contact. Consider the wide operating temperature range if the environment exceeds standard commercial limits.

Single Diodes Part Context

This component belongs to the family of standard silicon power rectifiers utilizing the legacy DO-5 axial leaded or stud mount package style. These devices are commonly found in older industrial equipment and heavy-duty power supplies where mechanical stability and thermal performance are prioritized over compact surface-mount solutions.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers producing the 1N2794 specification, such as Microsemi or New Jersey Semi-Conductor, to ensure pinout and mechanical dimensions match. Verify that substitute parts meet the same 5A current and 100V voltage ratings.
