UF4006

Single Diodes Overview

The UF4006 is a high-efficiency rectifier from the UF4001–UF4007 series by Taiwan Semiconductor Corporation. It features an 800V repetitive peak reverse voltage (VRRM) and a 560V total RMS reverse voltage rating. The device supports a continuous forward current (IF) of 1A with a maximum surge current (IFSM) of 30A. Electrical characteristics include a typical forward voltage (VF) of 1.7V at 1A, a reverse leakage current (IR) of 5µA at rated VR, and a reverse recovery time (trr) of 75ns. It operates within a junction temperature range of -55°C to +150°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging type and AEC-Q101 automotive qualification status. Standard versions are available in tape and reel or ammo box formats. Confirm that the component meets RoHS and halogen-free requirements as specified in IEC 61249-2-21 before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component for applications requiring 800V blocking capability and fast recovery characteristics. Ensure the operating junction temperature remains within the -55°C to +150°C range. Consider thermal resistance values for heat dissipation planning. Verify if AEC-Q101 qualification is required for the target environment, as indicated by specific ordering codes.

Single Diodes Part Context

This part belongs to the UF4001 through UF4007 series of 1A high-efficiency rectifiers manufactured by Taiwan Semiconductor Corporation. The series covers voltage ratings from 50V to 1000V, utilizing a DO-204AL (DO-41) axial leaded package. The UF4006 specifically provides the 800V variant within this standardized lineup designed for general-purpose high-frequency rectification.

Single Diodes Replacement Considerations

Compatible substitutes include other 1A, 800V ultrafast recovery rectifiers in the DO-41 package. Verify matching electrical parameters such as reverse recovery time and forward voltage drop. Ensure mechanical dimensions and pinout compatibility for direct replacement in existing PCB layouts.
