Overview
The Microchip Technology 1N6666 is a general-purpose ultra-fast rectifier diode designed for through-hole mounting in the TO-257 (TO-204AA) package. It features a peak repetitive reverse voltage of 200V and an average forward current rating of 10A. The device exhibits a maximum forward voltage drop of 1V at rated current and a fast reverse recovery time of 35ns, making it suitable for high-speed switching applications requiring reliable power conversion.
Feature Summary
- Ultra-fast rectification capability with reduced reverse recovery time
- High surge current handling capacity for robust operation
- General-purpose design for versatile power supply applications
Applications
- High-frequency power supply rectification
- DC-DC converter output stages
- Free-wheeling diodes in inductive load circuits
Procurement Notes
Verify the manufacturer origin, as the 1N6666 designation is historically associated with multiple vendors including Microsemi and New Jersey Semi-Conductor. Confirm that the specific unit received matches the required electrical specifications, particularly the 200V rating and 10A current capacity, to ensure compatibility with the target circuit design.
Selection Notes
Select this component when a standard ultra-fast rectifier is needed for low-voltage, high-current applications. Ensure the operating environment stays within the specified temperature range and that the PCB layout supports the thermal requirements of the TO-257 package for adequate heat dissipation during continuous operation.
Part Context
This component belongs to the standard military-style numbered diode series, commonly used in industrial and commercial electronics. It serves as a direct replacement for older silicon rectifiers in legacy designs while offering improved switching speeds compared to standard recovery devices.
Replacement Considerations
Check datasheets for equivalent parts from other manufacturers such as Microsemi or New Jersey Semi-Conductor to confirm pinout and electrical parameter compatibility before substitution.
