BAV99T-7

Overview

The BAV99T-7-F is a dual surface-mount fast switching diode from Diodes Incorporated, housed in an SOT523 package. It features a peak repetitive reverse voltage of 85 V and a forward continuous current rating of 155 mA per diode or 75 mA for the double configuration. The device exhibits a maximum reverse recovery time of 4.0 ns and a typical total capacitance of 0.81 pF at 1.0 MHz. Power dissipation is rated at 150 mW with a thermal resistance of 833 °C/W. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Ultra-small SOT523 surface-mount package designed for automated insertion
• Fast switching speed with low capacitance suitable for high-frequency applications
• High conductance characteristics for efficient signal handling
• Lead-free and RoHS compliant construction using halogen-free green materials

Applications

• General-purpose switching circuits
• High-speed signal processing
• Reverse polarity protection

Procurement Notes

Verify the specific ordering suffix against official documentation, as packaging quantities vary by suffix (e.g., -7-F indicates 3000 units per tape and reel). Confirm that the required automotive qualification status matches the project needs, noting that only the BAV99TQ variant holds AEC-Q101 qualification and PPAP capability. Ensure the selected part number aligns with the intended volume and carrier type requirements.

Selection Notes

Select this component for designs requiring compact footprint and rapid switching performance within standard industrial temperature ranges. Consider the BAV99TQ variant if automotive reliability standards and change control protocols are mandatory. Evaluate the 150 mW power dissipation limit against thermal constraints in densely packed PCB layouts. Verify compatibility with the SOT523 pad layout specifications provided in the datasheet.

Part Context

This device belongs to the BAS16T/BAW56T/BAV70T/BAV99T family of surface-mount fast switching diodes manufactured by Diodes Incorporated. All members share the same SOT523 mechanical outline and general feature set but differ in electrical parameters such as forward voltage and reverse voltage ratings. The BAV99T specifically targets general-purpose high-speed switching tasks.

Replacement Considerations

Cross-reference with other manufacturers offering dual series switching diodes in SOT523 packages. Verify that substitute parts meet the 85 V reverse voltage and 4 ns recovery time requirements. Note that only the BAV99TQ suffix denotes AEC-Q101 qualification; generic BAV99T equivalents may lack automotive certification.
