1N2059

Single Diodes Overview

The Microchip Technology 1N2059 is a silicon rectifier diode designed for high-current applications. It features a single-phase, single-element configuration housed in the DO-205AB (DO-9) axial leaded package with an isolated terminal connection. The device supports a maximum repetitive peak reverse voltage of 300V and handles a continuous average forward current of 275A. It exhibits a maximum non-repetitive peak forward surge current of 5000A and a maximum forward voltage drop of 1.3V. The component operates within a junction temperature range of -65°C to 190°C.

Single Diodes Procurement Notes

Verify compliance status as the component is identified as non-RoHS compliant. Confirm the specific suffix or revision level matches the required datasheet version. Ensure the DO-9 package dimensions align with the target PCB footprint. Check for any recent manufacturing change notices that may affect material composition or testing standards.

Single Diodes Selection Notes

Select this component when high average forward current and soft recovery characteristics are required. Compare against similar DO-9 rectifiers if higher voltage ratings are needed. Consider thermal management requirements due to the high current capacity. Verify that the 300V reverse voltage rating meets the circuit's peak inverse voltage demands.

Single Diodes Part Context

The 1N2059 belongs to the standard rectifier diode family from Microchip Technology. It shares the DO-205AB package form factor with other high-power diodes in the series. This part is distinct from low-voltage signal diodes and is intended for mains-frequency or low-frequency power conversion tasks.

Single Diodes Replacement Considerations

Consult official substitution lists for equivalent parts with matching current and voltage ratings. Verify pinout compatibility before replacing. Ensure the replacement maintains the same soft recovery profile if used in switching applications.
