Single Diodes Procurement Notes

Verify the specific ordering suffix and manufacturing lot details directly with authorized distributors or the manufacturer before procurement. Confirm compliance requirements such as RoHS status, as historical data indicates potential non-compliance with certain environmental directives. Ensure the component matches the exact electrical specifications required for the target circuit design.

Single Diodes Selection Notes

Select this component when a rugged, stud-mount rectifier is required for currents up to 3.3 A at voltages up to 200 V. Consider the physical mounting constraints of the DO-203AA package and the thermal resistance characteristics. Evaluate the standard recovery speed against application switching frequency requirements to ensure adequate performance without excessive reverse recovery losses.

Single Diodes Part Context

This part belongs to the 1N1124 series of axial and stud-mounted silicon rectifiers manufactured by Microchip Technology. These components are engineered for durability in demanding environments, offering reliable performance across a wide temperature range. The series is commonly utilized in legacy and industrial designs where through-hole or chassis-mounted solutions are preferred over surface-mount technologies.

Single Diodes Replacement Considerations

Consult official substitution guides for verified equivalents. Generic replacements must match the 200 V reverse voltage, 3.3 A current rating, and DO-203AA package form factor.
