Overview
The Microchip Technology 1N4528R is a standard recovery rectifier diode designed for high-power applications. It features an 800V maximum reverse voltage and supports a 90A average forward current. The device utilizes a DO-203AB (DO-5) screw-type package, ensuring robust mechanical stability for industrial environments. With a forward voltage drop of approximately 1.19V at rated conditions, it offers efficient power conversion capabilities suitable for demanding rectification tasks.
Feature Summary
- High current handling capability with 90A average rectified current rating
- Robust mechanical construction using screw-type mounting in DO-203AB package
- Standard recovery characteristics optimized for general-purpose rectification
Applications
- Industrial power supply rectification
- High-current DC power distribution systems
- Motor drive rectifier circuits
Procurement Notes
Verify the manufacturer marking matches Microchip Technology specifications. Confirm the DO-203AB package style and screw terminal configuration match your board design requirements. Ensure the 800V reverse voltage rating meets your circuit's peak inverse voltage demands. Check datasheet for thermal resistance values to validate heatsinking needs.
Selection Notes
Select this component when high current capacity and rugged packaging are required. The 800V rating suits medium-voltage AC-to-DC conversion. Consider the screw-mount form factor for high-vibration environments where leaded packages might fail. Evaluate thermal management strategies given the 90A current handling capability.
Part Context
This part belongs to the standard rectifier diode family from Microchip Technology, formerly Micrel. It serves as a high-power discrete semiconductor solution for industrial electronics. The 1N4528R designation follows traditional numbering conventions while meeting modern reliability standards for critical infrastructure components.
Replacement Considerations
Cross-reference with other 800V, 90A screw-mount rectifiers from manufacturers like Vishay or Littelfuse. Verify pinout compatibility and thermal performance metrics before substitution. Ensure replacement parts meet identical safety certifications if used in regulated equipment.
