Single Diodes Procurement Notes

Verify the specific suffix or variant against the official Microchip datasheet to ensure compatibility with your circuit requirements. Confirm that the stud mount interface matches your heatsink or chassis mounting hardware specifications. Check for any recent manufacturing changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Single Diodes Selection Notes

Select this component when high surge current handling and low forward voltage drop are critical for efficiency. Ensure the thermal design accommodates the power dissipation at the expected load current. Verify that the 200 V reverse voltage rating provides sufficient margin for the peak inverse voltage in the application circuit.
