Single Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required environmental standards and package variations. Confirm that the reel packaging format aligns with automated assembly equipment specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a standard silicon signal diode with moderate voltage blocking capability is required for through-hole designs. Ensure the circuit operates within the 165 mA forward current limit and does not exceed the 500 mW power dissipation threshold. Verify that the 150 V reverse voltage rating provides sufficient margin for the application's peak inverse voltage conditions.

Single Diodes Part Context

This part belongs to the broader category of discrete semiconductor diodes manufactured by Microchip Technology. It serves as a fundamental passive component in electronic assemblies, distinct from voltage reference or transient suppression devices. The DO-35 package is a standard industry form factor for small-signal axial components.

Single Diodes Replacement Considerations

Consult official substitution guides for equivalent signal diodes with matching voltage and current ratings. Verify pinout compatibility and thermal characteristics before integrating alternative manufacturers' parts into existing designs.
