BAS40Q-7-F

Single Diodes Overview

The BAS40Q-7-F is a surface-mount Schottky barrier diode manufactured by Diodes Incorporated. It features a single diode configuration housed in an SOT-23 (Standard) package. The device supports a peak repetitive reverse voltage of 40 V and a continuous forward current of 200 mA. Key electrical parameters include a maximum forward voltage of 1.0 V at 40 mA, a maximum reverse leakage current of 0.2 µA, and a reverse recovery time of 5 ns. It operates within a junction temperature range of -55°C to +125°C with a power dissipation rating of 350 mW.

Single Diodes Feature Summary

• Low forward voltage drop for improved efficiency
• Fast switching capability with 5 ns reverse recovery time
• PN junction guard ring design for transient and ESD protection

Single Diodes Applications

• Automotive applications requiring AEC-Q101 qualification
• General purpose rectification in surface-mount circuits
• High-frequency switching applications

Single Diodes Procurement Notes

Verify the component authenticity against Diodes Incorporated documentation. Confirm the specific suffix matches the required automotive grade (BAS40Q) rather than standard commercial variants. Ensure the ordering quantity aligns with the specified tape and reel packaging format. Cross-reference the date code and marking information to validate production batch details.

Single Diodes Selection Notes

Select this component when a low-capacitance Schottky diode is required for high-speed switching. The SOT-23 package offers space-saving benefits for compact designs. Consider the 40 V reverse voltage rating and 200 mA current capacity for load requirements. The AEC-Q101 qualification makes it suitable for automotive environments where reliability standards are strict.

Single Diodes Part Context

This part belongs to the BAS40 series of surface-mount Schottky barrier diodes. It shares the same core electrical specifications as the BAS40-7-F but includes the 'Q' designation indicating automotive qualification. The series utilizes silicon technology and is designed for general-purpose rectification tasks in modern electronic assemblies.

Single Diodes Replacement Considerations

Direct substitutes within the same family include BAS40-7-F for non-automotive use. Other variants like BAS40-04Q-7-F or BAS40-05Q-7-F offer different internal configurations while maintaining similar electrical characteristics. Verify package compatibility and thermal ratings before substitution.
