Procurement Notes
Verify the specific voltage variant required, as the 1N2813A designation covers a range of VRRM values from 50V to 400V. Confirm that the MIL-PRF-19500/308 qualification is necessary for the intended application. Ensure compatibility with the 50 Amp current rating and 150°C thermal limits during system design. Check for any specific lot traceability requirements mandated by the end-use industry.
Selection Notes
Select this component when military-grade reliability and fast recovery performance are required. Consider the specific VRRM rating needed for the circuit's peak inverse voltage. Evaluate the thermal management capabilities to ensure the 150°C junction temperature limit is not exceeded under maximum load conditions. Compare against standard commercial diodes if cost is a primary constraint and MIL-spec qualification is not mandatory.
Part Context
This component belongs to the 1N39xx series of high-reliability fast recovery rectifiers manufactured by Microchip Technology. It is part of a family of devices designed for rugged environments where standard commercial components may fail. The series includes multiple variants differentiated primarily by their peak repetitive reverse voltage ratings, allowing engineers to choose the appropriate breakdown voltage for their specific power supply or rectifier topology.
