1N2459

Single Diodes Overview

The Microchip Technology 1N2459 is a silicon power rectifier diode housed in the DO-5 (DO-203AB) package. It features a glass passivated die and glass-to-metal voltage construction. The component supports a repetitive peak reverse voltage (VRRM) of up to 1600V and offers a surge current rating of 1050 Amps. Classified as a standard rectifier with a reverse recovery time exceeding 500ns, it provides low forward voltage characteristics suitable for general-purpose power control applications.

Single Diodes Procurement Notes

Verify the manufacturer origin, as the 1N2459 designation has been associated with multiple entities including Microsemi and other brands. Confirm the specific datasheet version matches your design requirements regarding thermal and electrical limits. Ensure the package type corresponds to DO-5 (DO-203AB). Check for RoHS compliance status if required by your assembly specifications. Validate the part number against official Microchip or authorized distributor catalogs to avoid counterfeit components.

Single Diodes Selection Notes

Select this component when high reverse voltage blocking capability near 1600V is required alongside significant surge tolerance. The standard rectifier classification with slow recovery makes it appropriate for lower frequency switching applications where fast recovery is not critical. Consider the DO-5 package constraints for board space and mounting style. Evaluate thermal management needs based on the average forward current ratings specified in the official datasheet for your operating environment.

Single Diodes Part Context

The 1N2459 belongs to the family of silicon power rectifiers produced by Microchip Technology, formerly Microsemi. It is designed for robust performance in demanding power electronics environments. The device utilizes mature semiconductor manufacturing techniques to ensure consistent electrical characteristics. Its inclusion in the standard rectifier category indicates its role in fundamental power conversion tasks rather than specialized signal processing.

Single Diodes Replacement Considerations

Cross-reference with other 1600V DO-5 rectifiers from manufacturers like Vishay or ON Semiconductor. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement part meets or exceeds the 1050A surge rating and reverse voltage specifications.
