Procurement Notes
Verify the specific revision level and manufacturing lot traceability against the latest MIL-PRF-19500/642 datasheet requirements. Confirm that the procurement channel provides valid Certificate of Conformance and material declarations compliant with defense industry standards. Ensure compatibility with existing assembly processes regarding the TO-254 package form factor.
Selection Notes
Select this component when military qualification and ultrafast recovery characteristics are mandatory. The 1N6674R is suitable for designs requiring robust performance in high-temperature environments. Compare its 35 ns reverse recovery time against standard rectifiers to evaluate efficiency gains in high-speed switching topologies.
Part Context
This part belongs to the 1N676x series of dual ultrafast power rectifiers produced by Microchip Technology. The series includes variants such as 1N6762, 1N6763, and 1N6765, which share similar packaging and general electrical architectures but may differ in specific voltage or current ratings.
Replacement Considerations
Direct substitutes include other parts from the same MIL-PRF-19500/642 qualified family, specifically 1N6762, 1N6763, and 1N6765. Verify pinout compatibility and exact electrical parameter alignment before substitution.
