10CTQ150S

Overview

The 10CTQ150S is a Schottky barrier rectifier manufactured by SMC Diode Solutions. It features a common cathode dual configuration housed in a TO-263AB (D2PAK) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current of 10 A per diode. Key electrical characteristics include a forward voltage of 1.05 V at 10 A and a reverse leakage current of 100 µA at 150 V. It operates within a junction temperature range of -55°C to 175°C.

Feature Summary

• Schottky technology ensures low forward voltage drop for high efficiency
• Common cathode dual configuration simplifies circuit design
• High thermal stability supports operation up to 175°C junction temperature

Applications

• DC-DC converters
• Power supply units
• Free-wheeling diodes in inductive loads

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS3 directives and check for any lead-free plating requirements relevant to your assembly process. Cross-reference the manufacturer part number with authorized distributor databases to confirm current production status and availability.

Selection Notes

Select this component when a low-loss, high-speed rectification solution is required in a surface-mount format. The 150 V rating suits low-voltage DC conversion applications. Compare the 10 A current handling against thermal management capabilities in the final PCB layout. Consider the D2PAK footprint constraints and ensure adequate copper area for heat dissipation during continuous operation.

Part Context

This component belongs to the CTQ series of Schottky rectifiers from SMC Diode Solutions. The series offers various voltage ratings and current capacities in standardized surface-mount packages. These devices are designed to replace standard fast recovery diodes in applications where reduced switching losses and lower forward voltage are critical for system efficiency.

Replacement Considerations

Direct substitutes include the MBRS10150 from Taiwan Semiconductor Corporation, which shares identical 150 V, 10 A, and TO-263AB specifications.
