Overview
The 1N6661/TR is a standard recovery rectifier manufactured by Microchip Technology. It features a maximum DC reverse voltage of 225 V and an average forward current rating of 500 mA. The device utilizes a DO-204AH (DO-35) axial through-hole package. Key electrical characteristics include a forward voltage of 1 V at 400 mA, a reverse leakage current of 50 nA at 225 V, and a junction temperature range from -65°C to 175°C. It is supplied in tape and reel packaging.
Feature Summary
- Standard recovery speed classification suitable for general-purpose rectification applications
- Axial leaded construction designed for through-hole mounting on printed circuit boards
- Wide operating junction temperature range extending up to 175°C
Applications
- General purpose power supply rectification circuits
- Low voltage DC conversion stages
- Protection diodes in electronic control modules
Procurement Notes
Verify the specific suffix designation against official Microchip documentation to confirm packaging configuration. Confirm RoHS compliance status as regulatory requirements may vary by production lot. Ensure the ordering quantity aligns with the manufacturer's standard pack size to avoid partial reel handling issues during assembly.
Selection Notes
Select this component when a through-hole axial rectifier is required for moderate voltage levels around 225 V. The standard recovery time distinguishes it from fast recovery variants. Verify that the 500 mA current rating meets the peak load requirements of the target circuit design before finalizing the bill of materials.
Part Context
This part belongs to the 1N66xx series of discrete semiconductor rectifiers produced by Microchip Technology. The series offers various voltage ratings within the same mechanical form factor. The /TR suffix indicates the component is delivered in a continuous tape and reel format intended for automated surface mount or through-hole insertion machinery.
Replacement Considerations
Cross-reference with other manufacturers offering DO-35 packaged standard recovery diodes rated for 225 V and 500 mA. Verify pinout compatibility and thermal dissipation characteristics match the original design constraints.
