1N3671A

Single Diodes Overview

The GeneSiC Semiconductor 1N3671A is a silicon standard recovery diode housed in a DO-4 (DO-203AA) package. It supports a repetitive peak reverse voltage of 800 V and a continuous forward current of 12 A. The device features a maximum non-repetitive surge forward current of 240 A under half-sine wave conditions. Operating temperature ranges from -55 °C to 150 °C, with a storage temperature range of -55 °C to 150 °C. The junction-to-case thermal resistance is 1.1 °C/W.

Single Diodes Feature Summary

• High surge capability for handling transient current loads
• Not sensitive to electrostatic discharge
• Standard polarity configuration with stud as cathode

Single Diodes Applications

• Power supply rectification
• General purpose high voltage switching
• Industrial power control circuits

Single Diodes Procurement Notes

Verify the specific part marking matches the 1N3671A designation and confirm the terminal configuration aligns with standard polarity requirements where the stud serves as the cathode. Ensure the DO-4 package dimensions meet the mechanical constraints of the intended heatsink or mounting assembly before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when an 800 V blocking voltage and 12 A continuous current rating are required in a stud-mountable package. Consider the 1.1 °C/W thermal resistance for heat dissipation calculations. Verify that the -55 °C to 150 °C operating range satisfies the environmental conditions of the target application.

Single Diodes Part Context

This device belongs to the 1N3671A through 1N3673AR series of silicon standard recovery diodes. The series offers varying reverse voltage ratings from 800 V to 1000 V while maintaining consistent current handling capabilities. These components are designed for robust performance in industrial and power electronics applications requiring reliable rectification.

Single Diodes Replacement Considerations

Cross-reference with other 1N3671A variants from different manufacturers ensuring identical 800 V VRRM, 12 A IF, and DO-4 package compatibility. Verify thermal resistance and forward voltage characteristics match system design margins.
