1N6659

Overview

The Microchip Technology 1N6659 is a general-purpose rectifier diode array designed for high-current applications. It features a dual common cathode configuration housed in the U1 surface-mount package, which is a leadless 3-SMD type. The device supports a maximum repetitive reverse voltage of 200 V and provides an average forward rectified current of 15 A per diode. Key electrical characteristics include a forward voltage of 1 V at 10 A and a reverse leakage current of 10 µA at 200 V. The component exhibits a fast recovery time of 35 ns, making it suitable for efficient power conversion.

Feature Summary

• Dual common cathode configuration for compact circuit design
• High current handling capability with 15 A average forward rectified current rating
• Fast recovery performance with 35 ns reverse recovery time
• Surface-mount leadless package for automated assembly

Applications

• DC-DC converter circuits requiring high current efficiency
• Power supply output rectification stages
• Freewheeling diode applications in motor drives
• General purpose rectification in industrial electronics

Procurement Notes

Verify the specific suffix (e.g., U1) to confirm the package type and pinout, as standard 1N6659 may refer to through-hole variants. Confirm RoHS compliance status and manufacturing origin with the supplier. Ensure the ordering quantity matches the manufacturer's minimum order requirements for the specific tape-and-reel or bulk packaging option selected.

Selection Notes

Select this component when a dual common cathode arrangement is required to save board space compared to discrete diodes. The 15 A current rating makes it appropriate for medium-to-high power applications. Consider the 200 V reverse voltage limit to ensure compatibility with the system's peak inverse voltage. The surface-mount form factor aids in reducing the overall footprint of the power stage.

Part Context

The 1N6659 belongs to Microchip's family of general-purpose rectifier diodes. It is often grouped with similar high-current devices like the 1N6657 and 1N6658, which share comparable electrical characteristics but may differ in voltage ratings or package styles. This series is designed to replace older legacy parts in modern power electronics designs.

Replacement Considerations

Check datasheets for equivalent parts from other manufacturers offering 15 A, 200 V dual common cathode diodes in SMD packages. Verify that any substitute matches the 35 ns reverse recovery time and 1 V forward voltage specifications to maintain circuit performance.
