UF1B R0G

Single Diodes Overview

The UF1B R0G is a silicon ultra-fast rectifier manufactured by Taiwan Semiconductor Corporation. It features a single-phase configuration housed in a DO-204AL (DO-41) through-hole package. The device is rated for a maximum repetitive reverse voltage of 800V and conducts a continuous forward current of 1A. Key electrical characteristics include a fast recovery time of 75ns, a maximum forward voltage drop of 1.7V at rated current, and a low reverse leakage current of 5µA. It supports a maximum surge current of 30A and operates within a junction temperature range of -55°C to +150°C.

Single Diodes Procurement Notes

Verify the specific suffix 'R0G' against official Taiwan Semiconductor documentation to confirm packaging details and marking codes. Ensure the DO-204AL package type matches your PCB footprint requirements. Cross-reference the 800V rating and 1A current specifications with your circuit design constraints before finalizing procurement.

Single Diodes Selection Notes

Select this component when an ultra-fast recovery characteristic is required for 800V applications. The DO-204AL package is suitable for through-hole mounting where higher surge current tolerance is needed compared to surface-mount alternatives. Verify that the 1A continuous current rating meets the load requirements and that the 75ns recovery time aligns with the switching frequency of the target application.

Single Diodes Part Context

This part belongs to the UF1 series of ultra-fast rectifiers from Taiwan Semiconductor. The series typically offers various voltage ratings while maintaining consistent fast-recovery performance. The DO-204AL package provides a standard through-hole form factor widely used in industrial and consumer power electronics for reliable soldering and mechanical stability.

Single Diodes Replacement Considerations

Compatible substitutes must match the 800V reverse voltage, 1A forward current, and 75ns recovery time specifications. Verify pinout compatibility and package dimensions (DO-204AL) to ensure direct replacement without PCB modifications.
