1N3673A

Single Diodes Overview

The GeneSiC Semiconductor 1N3673A is a silicon standard recovery rectifier diode housed in a DO-4 (DO-203AA) stud mount package. It provides a continuous forward current of 12 A and supports a repetitive peak reverse voltage ranging from 800 V to 1000 V. The device features a high surge capability with a non-repetitive forward current rating of 240 A under half-sine wave conditions. It operates within a junction temperature range of -55 °C to 150 °C and includes a thermal resistance from junction to case of 2.00 °C/W.

Single Diodes Feature Summary

• High surge current capability for robust transient handling
• Not sensitive to electrostatic discharge events
• Standard polarity configuration with the stud terminal serving as the cathode

Single Diodes Applications

• Power supply rectification circuits
• Industrial power conversion systems
• General regulation applications requiring high voltage blocking

Single Diodes Procurement Notes

Verify the specific voltage rating required, as the datasheet covers a series from 800 V to 1000 V. Confirm the polarity configuration matches the design; the standard version has the stud as the cathode, while the 'R' suffix indicates the stud is the anode. Ensure mounting hardware accommodates the 10-32 UNF thread on the stud terminal for proper mechanical attachment and thermal dissipation.

Single Diodes Selection Notes

Select this component when a single-phase rectifier with a 12 A average current rating is needed. The DO-4 package allows for direct stud mounting to heatsinks, simplifying thermal management in high-power environments. Consider the 150 °C maximum junction temperature limit for high-temperature operation scenarios where lower leakage currents are critical.

Single Diodes Part Context

This part belongs to the 1N3671A through 1N3673AR series of medium power silicon rectifiers. These devices are designed for general-purpose power applications requiring reliable performance under high voltage and current stress. The series utilizes a rugged DO-4 metal package to ensure durability and efficient heat transfer in demanding industrial settings.

Single Diodes Replacement Considerations

Cross-reference with other 12 A, 1000 V stud-mount rectifiers in the DO-4 package. Verify that substitute parts match the 10-32 UNF thread size and thermal resistance specifications to maintain system cooling efficiency.
