Single Diodes Procurement Notes

Verify the specific suffix or variant against the official Microchip datasheet to ensure compatibility with required thermal and electrical specifications. Confirm package mounting hole dimensions and torque requirements for proper installation. Check for any recent product change notifications regarding material composition or testing standards before finalizing procurement.

Single Diodes Selection Notes

Select this component for applications requiring high voltage isolation and significant current capacity in a compact stud-mount form factor. Ensure the cooling solution can handle the thermal load associated with 40 A operation. Verify that the system's peak inverse voltage does not exceed the 1000 V rating under all operating conditions.

Single Diodes Part Context

The 1N2287 belongs to Microchip's discrete diode portfolio, specifically designed for general-purpose rectification in power electronics. It utilizes silicon technology to provide reliable performance in demanding environments. The DO-5 package allows for direct mounting to heat sinks, facilitating effective heat transfer in high-power circuits.

Single Diodes Replacement Considerations

Direct replacements must match the 1000 V reverse voltage, 40 A current rating, and DO-5 stud mount package. Verify forward voltage characteristics and thermal resistance values to ensure equivalent performance. Consult manufacturer cross-reference lists for approved equivalents.
