1N3767

Single Diodes Overview

The Microchip Technology 1N3767 is a silicon standard recovery rectifier diode housed in a DO-5 (DO-203AB) stud-mount package. It features a maximum repetitive peak reverse voltage of 900 V and an average forward rectified current rating of 35 A. The device exhibits a maximum forward voltage drop of 1.2 V at the rated current and supports a non-repetitive peak surge current of up to 475 A. It operates within a junction temperature range of -65°C to 190°C, ensuring reliability in high-temperature environments.

Single Diodes Feature Summary

• High thermal stability with a maximum junction temperature of 190°C
• Robust surge current handling capability for transient protection
• Stud-mount construction for efficient chassis heat dissipation

Single Diodes Applications

• General purpose power rectification
• Industrial power supplies
• Battery charging circuits

Single Diodes Procurement Notes

Verify the manufacturer origin carefully, as the 1N3767 designation is historically associated with multiple vendors including Vishay and GeneSiC. Confirm that the specific lot matches Microchip Technology specifications if required by design. Ensure the DO-5 package dimensions and terminal plating meet mechanical integration requirements. Check RoHS compliance status against project constraints.

Single Diodes Selection Notes

Select this component when a high-voltage, medium-current rectifier with superior thermal performance is needed. The 900V rating provides safety margin for higher voltage systems. The stud-mount package is suitable for applications requiring direct mounting to heatsinks or chassis for effective thermal management compared to leaded packages.

Single Diodes Part Context

The 1N3767 belongs to the legacy general-purpose rectifier family, often grouped with similar ratings like the 1N3765 through 1N3768 series. These components are widely used in industrial and military-grade electronics where long-term reliability and high-temperature operation are critical. The DO-5 package remains a standard form factor for stud-mounted power diodes.

Single Diodes Replacement Considerations

Cross-reference with Vishay VS-1N3767 or GeneSiC 1N3767 equivalents. Verify electrical parameters such as Vf and leakage current match system requirements. Ensure mechanical compatibility of the stud mount interface and terminal configuration before substitution.
