1N6768R

Overview

The Microchip Technology 1N6768R is a dual ultrafast power rectifier qualified under MIL-PRF-19500/642. It features a 600V reverse voltage rating and a 3.0A average forward current per diode in a TO-254AA package. The device exhibits a 50ns maximum reverse recovery time and a soft recovery characteristic to minimize switching losses and electromagnetic interference.

Feature Summary

• Dual ultrafast power rectifier configuration
• Qualified per MIL-PRF-19500/642 standards
• Soft recovery characteristic for reduced EMI

Applications

• High-frequency switch-mode power supplies
• Power factor correction circuits
• Communication power modules

Procurement Notes

Verify the specific suffix 'R' against the official datasheet to confirm it denotes the reel packaging variant rather than a functional change. Ensure procurement channels source directly from authorized distributors or the manufacturer to guarantee authenticity, as this component is subject to military qualification standards.

Selection Notes

Select this component for designs requiring high-efficiency rectification at frequencies ranging from tens to hundreds of kilohertz. The 600V rating provides adequate margin for bus voltages exceeding 400V when combined with snubber circuits. Evaluate thermal management requirements based on the specified junction-to-ambient thermal resistance.

Part Context

This part belongs to the 1N676x series of dual ultrafast rectifiers manufactured by Microchip Technology. The series includes variants such as the 1N6762, 1N6763, 1N6764, and 1N6765, which share similar ultrafast recovery characteristics but differ in voltage and current ratings.

Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers within the same family. Verify that any replacement maintains the required MIL-PRF-19500/642 qualification if military-grade reliability is mandated.
