1N3660

Single Diodes Overview

The 1N3660 is a standard recovery rectifier manufactured by Microchip Technology, designed for high-current applications. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current rating of 35 A. The device utilizes a DO-21 (DO-208AA) stud mount package, suitable for robust industrial environments. Electrical characteristics include a forward voltage drop of 1.1 V at the rated current and a maximum reverse leakage current of 10 µA at 100 V. The component supports a junction temperature range from -65°C to 175°C.

Single Diodes Feature Summary

• High current handling capability with a 35 A average forward rectified current rating
• Robust thermal performance supporting junction temperatures up to 175°C
• Stud mount construction in a DO-21 package for secure mechanical installation

Single Diodes Applications

• Battery charging systems
• DC motor drive rectification

Single Diodes Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Microchip Technology before procurement. Confirm that the DO-21 stud mount interface matches the heatsink or chassis mounting requirements of the target design. Ensure that the 100 V reverse voltage rating provides adequate margin for the peak inverse voltage present in the application circuit to prevent breakdown.

Single Diodes Selection Notes

Select this component when a single-phase standard recovery rectifier is required for currents exceeding typical through-hole limits. The 100 V rating suits low-voltage AC-to-DC conversion stages. Consider the thermal resistance of the mounting surface, as the 35 A current generates significant heat. Verify that the system operates within the specified -65°C to 175°C junction temperature range under all expected load conditions.

Single Diodes Part Context

This part belongs to the Microchip S/R35PF series of standard recovery rectifiers. These devices are engineered for general-purpose rectification in power electronics. The series offers a balance of switching speed and current capacity, utilizing silicon planar technology. The DO-21 package allows for direct mounting to cold plates or chassis structures for efficient heat dissipation.

Single Diodes Replacement Considerations

Cross-reference with other 35 A, 100 V stud-mount rectifiers from manufacturers such as Vishay or Littelfuse. Ensure equivalent forward voltage and reverse leakage specifications to maintain thermal and electrical performance parity.
