Overview
The 10DQ03 is a Schottky barrier rectifier manufactured by SMC Diode Solutions. It features a maximum DC reverse voltage (Vr) of 30 V and an average forward rectified current (Io) of 1 A. The device utilizes DO-41 through-hole packaging. Key electrical parameters include a forward voltage (Vf) of 850 mV at 1 A and a reverse leakage current of 5 µA at 30 V. The junction temperature range spans from -55°C to +175°C, ensuring reliable operation in various thermal environments.
Feature Summary
- Schottky barrier technology for high efficiency and low power loss
- Guard ring die construction provides transient protection
- High current capability within the DO-41 package
Applications
- General purpose rectification in low voltage circuits
- Power supply input stages
- Free-wheeling diodes in inductive load circuits
Procurement Notes
Verify the specific suffix or tape/reel designation if automated assembly is required, as standard DO-41 packages may vary in bulk or cut-tape formats. Confirm RoHS compliance status with the supplier for environmental regulations. Ensure the ordering part number matches the exact Vf and leakage specifications required for the target application circuit design.
Selection Notes
Select this component when a fast-switching rectifier is needed for 30 V applications with currents up to 1 A. The Schottky structure offers lower forward voltage drop compared to standard PN junction diodes, improving overall system efficiency. The DO-41 package allows for easy integration into through-hole PCB designs without requiring specialized surface mount equipment.
Part Context
This part belongs to the 10DQ series of Schottky rectifiers from SMC Diode Solutions. The series typically includes variants with different voltage ratings while maintaining similar current handling capabilities. These devices are designed for general-purpose use where speed and efficiency are prioritized over high reverse voltage blocking.
Replacement Considerations
Direct replacements must match the 30 V rating, 1 A current capacity, and DO-41 package. Verify that substitute Schottky diodes have comparable forward voltage characteristics and reverse leakage limits to maintain circuit performance.
