Single Diodes Procurement Notes

Verify the manufacturer source carefully, as multiple entities including Central Semiconductor and New Jersey Semi-Conductor produce this part number. Confirm the specific datasheet version matches your required electrical tolerances and packaging specifications before ordering.

Single Diodes Selection Notes

Select this component when an 80 V reverse voltage rating and 500 mA forward current are sufficient for the circuit requirements. Ensure the axial leaded form factor aligns with the available board space and mounting constraints of the design.

Single Diodes Part Context

This part belongs to the standard rectifier diode category. While marketed by Microchip Technology, the 1N3666 designation is also utilized by other manufacturers such as Central Semiconductor Corp., indicating a common industry specification rather than a unique proprietary device.

Single Diodes Replacement Considerations

Check for equivalents from Central Semiconductor or New Jersey Semi-Conductor. Verify that substitute parts maintain the 80 V reverse voltage and 500 mA current ratings to ensure functional compatibility.
