UF1003-T

Single Diodes Overview

The UF1003-T is a 1.0A ultra-fast rectifier from Diodes Incorporated, designed for high-efficiency switching applications. It features a peak repetitive reverse voltage of 200V and an average rectified output current of 1.0A at 55°C. The device exhibits a maximum forward voltage of 1.7V at 1.0A and a typical reverse recovery time of 50ns. It supports a non-repetitive peak forward surge current of 30A and operates within a junction temperature range of -65°C to +150°C.

Single Diodes Feature Summary

• Ultra-fast switching capability for high efficiency
• Low reverse leakage current
• Surge overload rating to 30A peak
• Plastic material with UL flammability classification rating 94V-0

Single Diodes Applications

• High frequency switching power supplies
• Free-wheeling diodes in DC-DC converters
• Polarity protection circuits

Single Diodes Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as standard distribution may vary between tape-and-reel and cut-tape options. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the supplier provides valid traceability documentation consistent with Diodes Incorporated manufacturing standards.

Single Diodes Selection Notes

Select this component when a 200V blocking voltage and 1.0A continuous current are required in a DO-41 axial package. Consider the 50ns reverse recovery time for high-frequency operation where standard rectifiers would cause excessive losses. Evaluate thermal derating curves if ambient temperatures exceed 55°C to maintain the rated 1.0A current capacity.

Single Diodes Part Context

This part belongs to the UF1001-U1007 series of ultra-fast rectifiers, differentiated primarily by their reverse voltage ratings ranging from 50V to 1000V. All variants share identical current handling and physical package characteristics. The UF1003 specifically targets applications requiring 200V isolation while maintaining fast recovery speeds.

Single Diodes Replacement Considerations

Direct substitutes include UF1002 (100V) or UF1004 (400V) if voltage margins allow. Cross-manufacturer equivalents such as FR107 or UF4007 may be considered but require verification of reverse recovery time and forward voltage specifications against the original datasheet.
