1N4510

Overview

The Microchip Technology 1N4510 is a standard silicon power rectifier diode housed in the DO-4 (DO-203AA) stud mount package. It features a glass-to-metal seal construction with a glass-passivated die for enhanced reliability. The device supports a maximum repetitive peak reverse voltage of 1000 V and handles a maximum non-repetitive peak forward surge current of 250 A. Designed for single-phase applications, it utilizes a solder lug terminal configuration on an upper position within a round metal post-mount form factor.

Feature Summary

• Glass-to-metal seal construction providing robust environmental protection
• Glass passivated die ensuring stable electrical characteristics
• Stud mount design facilitating efficient thermal dissipation
• High surge current capability for demanding power applications

Applications

• Power supply circuits requiring high voltage rectification
• Industrial power conversion systems
• General purpose high-voltage rectification tasks

Procurement Notes

Verify the specific voltage rating variant, as datasheets indicate VRRM options up to 1600 V while some listings specify 1000 V. Confirm RoHS compliance status, as this component is often categorized under non-RoHS packages. Ensure the DO-4 stud mount interface matches your thermal management requirements. Cross-reference manufacturer part numbers between Microchip and legacy Microsemi sources to confirm exact specifications before procurement.

Selection Notes

Select this component when a rugged, stud-mounted silicon rectifier is required for high-voltage DC applications. The DO-4 package offers superior heat sinking compared to axial leads. Consider the 250 A surge rating for inrush current handling. Verify that the 1000 V or higher reverse voltage rating aligns with the circuit's peak inverse voltage requirements. Ensure mounting hardware accommodates the single solder lug terminal.

Part Context

The 1N4510 belongs to the family of standard silicon power rectifiers manufactured by Microchip Technology, formerly Microsemi. These components are designed for general-purpose rectification in industrial and commercial power electronics. The DO-4 package is a traditional metal stud mount style, distinct from modern surface-mount technologies. This series emphasizes durability and high surge capacity over miniaturization.

Replacement Considerations

Check for direct equivalents from other manufacturers offering identical DO-4 stud mount dimensions and 1000 V minimum reverse voltage ratings. Ensure substitute parts maintain the 250 A surge current capability. Verify that any replacement also utilizes glass-passivated die technology for comparable reliability.
