1N4530

Single Diodes Overview

The Microchip Technology 1N4530 is a silicon rectifier diode housed in the DO-5 axial leaded package. It is designed for general-purpose rectification applications requiring high voltage and current handling capabilities. The component features a peak repetitive reverse voltage of 1200V and an average forward rectified current rating of 40A at 75°C. It exhibits a maximum non-repetitive surge current capability of 400A for one cycle at 60Hz. The device operates with a low forward voltage drop and maintains reliable performance across a wide junction temperature range from -65°C to +175°C.

Single Diodes Procurement Notes

Verify the specific manufacturer source, as New Jersey Semi-Conductor Products also produces this part number under license or historical designation. Confirm RoHS compliance status if required by your assembly process, noting that some listings indicate non-RoHS variants. Ensure the DO-5 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when circuit design requires a single-phase silicon rectifier capable of handling 1200V reverse voltage and 40A continuous current. Consider the DO-5 package size constraints and axial lead configuration for through-hole mounting. Evaluate thermal management needs given the 40A rating and ensure the ambient temperature does not exceed the derating curve limits specified in the official datasheet.

Single Diodes Part Context

The 1N4530 belongs to the standard silicon rectifier family, historically associated with New Jersey Semi-Conductor Products and currently manufactured by Microchip Technology. It serves as a rugged discrete semiconductor solution for industrial and commercial power electronics. The DO-5 package provides mechanical robustness for high-current applications where surface-mount alternatives may be insufficient.

Single Diodes Replacement Considerations

Direct substitutes include other 1200V 40A DO-5 silicon rectifiers such as the 1N4530 equivalents from New Jersey Semi-Conductor. Verify pinout compatibility and thermal characteristics before swapping manufacturers.
