Single Diodes Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or certified suppliers. Confirm that the received parts match the 1N3212R designation and DO-203AB package style. Check manufacturing dates against relevant product change notices to ensure compliance with current specifications. Validate that the components meet the required electrical parameters before integration into final assemblies.

Single Diodes Selection Notes

Select this component when a 400 V reverse voltage rating and 40 A continuous current capacity are required. The DO-203AB package facilitates direct stud mounting for efficient heat dissipation. Consider the 200°C junction temperature limit for high-temperature environments. Ensure the circuit design accommodates the standard recovery time characteristics for the intended switching frequency.

Single Diodes Part Context
