Procurement Notes
Verify the specific suffix designation against official Microchip documentation to confirm tape-and-reel packaging configuration. Ensure that the required electrical parameters align precisely with the circuit design requirements before finalizing procurement decisions. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.
Selection Notes
Select this component when a standard recovery silicon junction diode is required for low-power signal applications. Consider the 70 V reverse voltage limit and 100 mA forward current capacity during circuit planning. Evaluate the thermal management needs relative to the 500 mW power dissipation capability in the specified operating environment.
Part Context
This device belongs to the standard rectifier and diode product family offered by Microchip Technology. It serves as a fundamental discrete semiconductor component used in various electronic assemblies. The part represents a legacy industry-standard designation adapted for modern manufacturing processes and supply chain requirements.
Replacement Considerations
