Overview
The 1N4587 is a silicon rectifier diode manufactured by Microchip Technology. It features a maximum average forward rectified current of 150 A and a repetitive peak reverse voltage of 100 V. The device utilizes a DO-205AA (DO-8) package with a cathode-connected case. Key electrical parameters include a maximum non-repetitive peak forward surge current of 2500 A, a maximum forward voltage of 1.4 V, and an operating temperature range extending up to 200 °C.
Feature Summary
- High current handling capability for power rectification applications
- Robust surge current tolerance for transient protection
- Extended thermal stability for high-temperature environments
Applications
- Soft recovery power circuits
- General purpose rectification in industrial equipment
- Power supply input stages
Procurement Notes
Verify the specific manufacturer source, as the component history involves Microsemi and Microchip Technology. Confirm RoHS compliance status, as some sources indicate non-compliance while others suggest compliant variants exist. Ensure the package code matches DO-205AA or DO-8 specifications required for your PCB footprint and mounting constraints.
Selection Notes
Select this component when a standard silicon rectifier with 150 A continuous current rating is required. The 100 V reverse voltage rating suits low-voltage AC-to-DC conversion tasks. Consider the DO-8 package size for mechanical integration and verify that the 1.4 V forward voltage drop aligns with system efficiency targets.
Part Context
This part belongs to the standard rectifier diode family, historically associated with Microsemi Corporation before its acquisition by Microchip Technology. It serves as a general-purpose power diode designed for robust performance in demanding electrical environments. The component maintains legacy designations while adhering to modern manufacturing standards.
Replacement Considerations
Consult official datasheets for direct substitutes within the same current and voltage ratings. Verify pinout compatibility and thermal characteristics before swapping manufacturers.
