1N3167

Single Diodes Overview

The 1N3167 is a standard recovery rectifier diode manufactured by Microchip Technology. It features a maximum repetitive peak reverse voltage of 350 V and an average forward rectified current rating of 240 A. The device utilizes a DO-205AB (DO-9) axial leaded package suitable for panel or chassis mounting. Key electrical characteristics include a maximum DC reverse leakage current of 75 µA at 350 V and a typical forward voltage drop of 1.25 V at the rated current. The junction temperature range spans from -65°C to +200°C, supporting operation in demanding thermal environments.

Single Diodes Feature Summary

• Robust reverse blocking performance with a 350 V maximum repetitive peak reverse voltage
• Extended thermal stability allowing junction temperatures up to +200°C
• Standard axial leaded construction for secure mechanical mounting

Single Diodes Applications

• Industrial power supply rectification circuits
• Battery charging systems requiring high current throughput
• Welding equipment power stages
• DC motor drive output rectifiers

Single Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as 1N3167R may exist with identical core specifications but different packaging or qualification levels. Confirm RoHS compliance status directly with the manufacturer, as commercial versions may differ from qualified military grades. Ensure the selected package matches the required mounting style, as this component typically requires through-hole or stud mounting rather than surface mount techniques.

Single Diodes Selection Notes

Select this component for applications necessitating high surge current capacity and robust reverse voltage tolerance. The wide operating temperature range makes it suitable for harsh industrial environments where standard silicon limits might be exceeded. Evaluate the thermal management requirements carefully, as the high forward current generates significant heat that must be dissipated effectively through the lead frame or mounting hardware to maintain reliability within the specified junction temperature limits.

Single Diodes Part Context

The 1N3167 belongs to the broader family of standard recovery rectifiers produced by Microchip Technology. These devices are designed for general-purpose power conversion tasks where high current density is critical. The product line emphasizes durability and consistent electrical performance across varying load conditions, serving as a foundational component in heavy-duty electronic power systems.

Single Diodes Replacement Considerations

Consult official cross-reference guides for equivalent parts offering matching 240 A current ratings and 350 V reverse voltage capabilities. Ensure any substitute maintains the same DO-205AB package dimensions and pin configuration to fit existing board layouts without modification.
