Overview
The 10DQ04 is a Schottky barrier rectifier manufactured by SMC Diode Solutions, housed in the DO-41 (DO-204AL) axial leaded package. It features a maximum average forward rectified current of 1A and a maximum repetitive peak reverse voltage of 40V. The device utilizes a chip guard ring die construction for enhanced transient protection. Key electrical specifications include a maximum DC reverse voltage of 40V, an average rectified output current of 1A, and a maximum forward voltage drop of 550mV at 1A.
Feature Summary
- Schottky barrier technology ensures low power loss and high efficiency during operation.
- Chip guard ring die construction provides robust protection against transient voltage events.
- Axial leaded package design facilitates through-hole mounting on printed circuit boards.
Applications
- General purpose rectification in low-voltage power supply circuits
- Free-wheeling diodes in inductive load switching applications
- Clamping diodes in protection circuits requiring fast recovery characteristics
Procurement Notes
Verify the manufacturer marking matches SMC Diode Solutions to ensure authenticity. Confirm the package type is DO-41/DO-204AL with axial leads. Check datasheet revisions for any updates to thermal resistance or maximum ratings. Ensure storage conditions comply with moisture sensitivity levels if applicable. Validate part status as active before finalizing procurement plans.
Selection Notes
Select this component when a low forward voltage drop is critical for system efficiency. The 40V rating suits applications with moderate reverse voltage requirements. Consider the 1A current limit for small signal or low-power rectification tasks. The axial package is suitable for manual assembly or automated through-hole processes where surface mount options are not required.
Part Context
This component belongs to the 10DQ series of Schottky rectifiers from SMC Diode Solutions. The series typically includes variants with different reverse voltage ratings while maintaining similar current handling capabilities. These devices are designed for general-purpose use where speed and efficiency are prioritized over high voltage blocking capability.
Replacement Considerations
Direct substitutes must match the 1A current, 40V reverse voltage, and DO-41 package. Verify that alternative Schottky diodes maintain comparable forward voltage characteristics. Ensure pinout compatibility for axial leaded configurations. Cross-reference thermal performance data to guarantee equivalent heat dissipation capabilities in the target application.
