1N4590R

Single Diodes Overview

The Microchip Technology 1N4590R is a standard recovery rectifier diode designed for general-purpose applications. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 150 A. The device utilizes a DO-205AA (DO-8) chassis mount package, facilitating robust thermal management and high-current handling capabilities in industrial power conversion systems.

Single Diodes Feature Summary

• Standard recovery characteristics suitable for general-purpose rectification
• High current capacity with 150 A average forward current rating
• Robust chassis mount construction for efficient heat dissipation

Single Diodes Applications

• Industrial power supplies
• Motor drive rectification
• General-purpose AC to DC conversion

Single Diodes Procurement Notes

Verify the manufacturer source carefully as multiple entities including GeneSiC, Navitas, and Powerex list this part number. Confirm the specific datasheet version matches Microchip Technology specifications. Check for obsolescence status as some distributors indicate scheduled discontinuation. Ensure the DO-205AA package dimensions align with your mechanical design requirements before ordering.

Single Diodes Selection Notes

Select this component when a standard recovery time is sufficient for the switching frequency. The 400 V rating provides adequate margin for common three-phase bridge configurations. Consider the chassis mount requirement for PCB layout, as surface-mount alternatives are not available in this specific form factor. Evaluate thermal resistance values from the official datasheet for heatsink design.

Single Diodes Part Context

This diode belongs to the 1N4590 series of silicon rectifiers. It is historically associated with Powerex and later acquired by Microchip Technology. The 'R' suffix typically denotes a specific tape and reel or packaging variation, though verification against the specific Microchip datasheet is required to confirm functional differences compared to non-R variants.

Single Diodes Replacement Considerations

Cross-reference with other 1N4590 series parts from different manufacturers such as GeneSiC or Navitas. Verify that replacement units maintain the same 400 V / 150 A ratings and DO-205AA footprint. Confirm that standard recovery characteristics meet the circuit's reverse recovery time requirements.
