1N3659R

Single Diodes Overview

The 1N3659R is a silicon power rectifier manufactured by Microchip Technology, formerly associated with Motorola and Microsemi. It features a press-fit DO-21 package (also known as DO-208) designed for high-current applications. The device provides a maximum repetitive peak reverse voltage of 50V and an average forward rectified current rating of 35A. It includes a surge current rating of 400A and utilizes glass passivation for the die to ensure low leakage current and soft recovery characteristics.

Single Diodes Feature Summary

• Glass passivated die construction for enhanced reliability
• Soft recovery characteristics to minimize switching noise
• High surge current capability for robust operation

Single Diodes Applications

• Industrial power supplies
• Battery charging circuits
• General-purpose rectification in low-voltage DC systems

Single Diodes Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot codes and date codes against current production standards. Note that this part may be discontinued or subject to last-time buy status depending on the specific manufacturing lineage. Request detailed datasheets to confirm electrical parameters match system requirements before procurement.

Single Diodes Selection Notes

Select this component when a 35A continuous current rating and 50V blocking voltage are required in a press-fit form factor. Ensure thermal management strategies account for the specific mounting constraints of the DO-21 package. Compare alternative packages if board space or mounting method differs from press-fit requirements.

Single Diodes Part Context

This diode belongs to the standard silicon rectifier family, historically produced by Motorola Semiconductor and later acquired by Microsemi, now part of Microchip Technology. The 1N3659 series is characterized by its ability to handle significant forward currents while maintaining low reverse leakage, making it suitable for industrial environments where reliability under stress is critical.

Single Diodes Replacement Considerations

Direct substitutes include other 1N3659 variants from different manufacturers such as Vishay or STMicroelectronics, provided they meet the 35A/50V specification and DO-21 package dimensions. Verify pinout compatibility and thermal resistance values before substitution.
