BAT64Q-13-F

Single Diodes Overview

The BAT64Q-13-F is a surface-mount Schottky barrier diode manufactured by Diodes Incorporated, housed in an SOT23 package. It features a peak repetitive reverse voltage of 40 V and an average rectified output current of 250 mA. The forward voltage reaches a maximum of 750 mV at a forward current of 100 mA, with a reverse leakage current limited to 2 µA at 40 V. The device supports a non-repetitive peak forward surge current of 2,100 mA and operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

Single Diodes Applications

• Automotive electronics requiring AEC-Q101 qualification
• General-purpose rectification in surface-mount circuits
• Clamping and protection in low-voltage signal paths

Single Diodes Procurement Notes

Verify the specific ordering suffix matches the required packing quantity, as the -13-F suffix indicates a 10,000-unit tape and reel configuration. Confirm that the component meets RoHS 3 and halogen-free requirements if environmental compliance is mandatory for the target assembly process. Ensure the design accommodates the specified thermal resistance and derating curves for reliable operation under expected load conditions.

Single Diodes Selection Notes

Select this component when a compact SOT23 footprint is required alongside fast switching speeds and robust transient protection capabilities. The 40 V rating suits low-voltage DC-DC converters and signal processing stages. Consider the 250 mA continuous current limit and ensure adequate thermal management on the PCB to maintain performance within the specified operating temperature range.

Single Diodes Part Context

This part belongs to the BAT64Q/AQ/CQ/SQ family of surface-mount Schottky barrier diodes. All variants share identical electrical characteristics but differ in automotive qualification levels and manufacturing controls. The BAT64Q variant provides standard commercial specifications, while other suffixes denote enhanced reliability standards suitable for stricter industrial or automotive environments.

Single Diodes Replacement Considerations

Direct substitutes within the same family include BAT64AQ-13-F, BAT64CQ-13-F, and BAT64SQ-13-F. These alternatives offer identical pinouts and electrical parameters but may provide different levels of automotive qualification or change control documentation. Verify package compatibility and thermal characteristics before substitution.
