10TQ045

Overview

The 10TQ045 is a Schottky barrier rectifier manufactured by SMC Diode Solutions, designed for high-efficiency power conversion applications. It features a dual common cathode configuration housed in a TO-263AB (D2PAK) surface-mount package. The device is rated for a maximum repetitive peak reverse voltage of 45 V and an average forward rectified current of 10 A per diode. Key electrical parameters include a maximum DC reverse leakage current of 1 mA at 45 V and a typical forward voltage drop of 580 mV at 10 A. The component operates within a junction temperature range of -55°C to 175°C and exhibits a maximum reverse recovery time of less than 500 ns.

Feature Summary

• Dual common cathode configuration enables efficient full-wave rectification in compact designs.
• High-temperature operation capability up to 175°C junction temperature ensures reliability under thermal stress.
• Low forward voltage drop minimizes conduction losses and improves overall system efficiency.
• Surface-mount D2PAK package provides robust mechanical strength and facilitates automated PCB assembly.

Applications

• DC-to-DC converters
• Power supply units
• Free-wheeling diodes in low-voltage circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout orientation and packaging type. Ensure that the procurement channel sources genuine components from authorized distributors to guarantee compliance with RoHS directives and prevent counterfeit parts. Cross-reference the part number with the latest SMC Diode Solutions documentation to validate current production status and availability constraints before finalizing orders.

Selection Notes

Select this component when designing systems requiring a dual common cathode arrangement with a 45 V reverse voltage rating. The 10 A current capacity makes it suitable for medium-power applications where space constraints favor surface-mount technology over through-hole packages. Consider the 175°C operating temperature limit for environments with elevated ambient temperatures or significant self-heating.

Part Context

This component belongs to the TQ series of Schottky rectifiers from SMC Diode Solutions, which are engineered for general-purpose rectification in switching power supplies. The series emphasizes low forward voltage and fast switching characteristics to reduce power dissipation. The 10TQ045 specifically targets applications needing dual-diode functionality in a single surface-mount footprint, balancing performance with board space efficiency.

Replacement Considerations

Consult the official SMC Diode Solutions cross-reference guide for verified substitutes. Ensure any replacement matches the 45 V reverse voltage, 10 A current rating, and TO-263AB package dimensions. Verify that alternative parts maintain equivalent thermal resistance and reverse leakage specifications to avoid derating issues in the final design.
