Single Diodes Procurement Notes

Verify the manufacturer designation carefully, as historical data links this part to Semiconductors Inc and Microsemi Corporation, while current listings indicate Microchip Technology. Confirm the specific datasheet version and package details (DO-205AA/DO-8 stud mount) match your mechanical requirements. Ensure the component meets the required thermal management specifications for the intended application environment.

Single Diodes Selection Notes

Select this component when a high-current, low-voltage rectifier with standard recovery speed is required. The 150 A rating and 200 V blocking voltage define its operational limits. Consider the DO-205AA stud mount package for efficient heat dissipation. The slow reverse recovery characteristic distinguishes it from fast-switching or Schottky alternatives, making it suitable for lower-frequency power conversion tasks.

Single Diodes Part Context

The 1N2439 belongs to the family of silicon power rectifiers manufactured by Microchip Technology. Historically associated with Microsemi Corporation and Semiconductors Inc, this part number represents a robust discrete semiconductor device. It is categorized under single-element rectifier diodes, utilizing a glass-passivated junction to withstand harsh electrical conditions in industrial settings.

Single Diodes Replacement Considerations

Direct substitutes must match the 150 A current, 200 V voltage, and DO-205AA package. Verify compatibility with standard recovery times exceeding 500 ns. Cross-reference with other 1N series rectifiers having identical electrical ratings and mounting configurations.
