Overview
The 11DQ09 is a single Schottky rectifier diode manufactured by SMC Diode Solutions. It features a maximum DC reverse voltage of 90 V and an average rectified current of 1.1 A. The device utilizes a DO-41 axial leaded package for through-hole mounting. Key electrical characteristics include a forward voltage of approximately 850 mV at 2 A (typical for the series) and a reverse leakage current of 500 µA at 90 V. The component operates within a junction temperature range of -55°C to 150°C.
Feature Summary
- Schottky barrier technology for low forward voltage drop and high switching efficiency
- High purity, high temperature epoxy encapsulation for enhanced mechanical strength
- Axial leaded outline designed for reliable through-hole mounting applications
Applications
- General purpose rectification in power supply circuits
- Free-wheeling diodes in inductive load protection
- DC-AC conversion stages requiring fast recovery characteristics
Procurement Notes
Verify the specific ordering suffix to ensure the correct packaging configuration, such as cut tape or tape and box, matches the assembly requirements. Confirm that the RoHS compliance status aligns with environmental regulations applicable to the final product deployment. Ensure the manufacturer part number corresponds exactly to the 11DQ09 specification sheet to avoid substitution errors in critical designs.
Selection Notes
Select this component when a through-hole Schottky rectifier is required for voltages up to 90 V and currents around 1.1 A. The axial package facilitates automated insertion or manual assembly on standard PCBs. Consider the thermal management capabilities provided by the epoxy encapsulation for environments with moderate heat dissipation needs.
Part Context
This component belongs to the DQ series of Schottky rectifiers from SMC Diode Solutions. The series offers various voltage ratings while maintaining consistent current handling and package styles. The 11DQ09 specifically targets applications needing a balance between low forward loss and robust mechanical packaging for axial lead implementations.
Replacement Considerations
Direct substitutes must match the 90 V reverse voltage, 1.1 A current rating, and DO-41 axial package. Verify pinout compatibility and thermal characteristics before implementation.
