Single Diodes Procurement Notes

Verify the manufacturer designation carefully, as this component has been produced by multiple entities including Navitas Semiconductor and Microsemi. Confirm the specific datasheet version matches your required electrical tolerances. Ensure the ordering suffix aligns with the exact RoHS status and packaging format needed for your assembly process. Cross-reference the part number against the current official Microchip Technology catalog to confirm active status and availability.

Single Diodes Selection Notes

Select this component when a 200 V reverse voltage rating and 6 A continuous current capacity are required in a stud-mount form factor. The 200 ns reverse recovery time makes it appropriate for applications needing faster switching than standard rectifiers but without the extreme speeds of ultra-fast variants. Evaluate the thermal resistance characteristics of the DO-4 package relative to your heatsinking strategy to ensure reliable operation within the specified temperature limits.

Single Diodes Part Context

This device belongs to the 1N388x series of high-power fast recovery rectifiers manufactured by Microchip Technology. The series typically offers various voltage ratings while maintaining consistent current handling and package styles.
