11DQ04

Overview

The 11DQ04 is a Schottky rectifier diode manufactured by SMC Diode Solutions, designed for high-efficiency power conversion applications. It features a maximum DC reverse voltage of 40 V and an average rectified forward current of 1.1 A. The device utilizes a DO-204AL (DO-41) axial through-hole package, facilitating easy integration into standard PCB layouts. Key electrical characteristics include a maximum forward voltage drop of 700 mV at the rated current and a low reverse leakage current of 500 µA at 50 V. The component supports a junction operating temperature range from -55°C to 150°C, ensuring reliable performance in demanding thermal environments.

Feature Summary

• Schottky barrier technology enables fast switching speeds with minimal reverse recovery time.
• Low forward voltage drop reduces conduction losses and improves overall system efficiency.
• Robust axial leaded construction provides mechanical stability for through-hole mounting.

Applications

• General-purpose rectification in AC/DC power supplies
• Free-wheeling diodes in DC/DC converters
• Polarity protection circuits in electronic devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and terminal finish specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the DigiKey part number 1801-SR105TR-ND or similar distributor identifiers with the official SMC Diode Solutions documentation to validate authenticity and exact component matching.

Selection Notes

Select this component when a through-hole Schottky diode with 40 V blocking capability and 1.1 A continuous current rating is required. Ensure the application circuit does not exceed the 150°C maximum junction temperature limit. Consider the 700 mV forward voltage drop impact on thermal management compared to lower-voltage-drop alternatives if efficiency is critical.

Part Context

The 11DQ04 belongs to the SMC Diode Solutions discrete semiconductor portfolio, which specializes in Schottky rectifiers and general-purpose diodes. This model is part of a series offering various voltage and current ratings within the DO-41 axial package format, catering to cost-sensitive and space-constrained consumer and industrial electronics designs requiring reliable rectification.

Replacement Considerations

Direct substitutes may include other 40 V, 1 A Schottky diodes in the DO-41 package, such as the SR105 from Taiwan Semiconductor Corporation, provided pin compatibility and electrical parameters align with the design requirements.
