BAV99-7-F-31

Overview

The BAV99-7-F-31 is a small signal switching diode array manufactured by Diodes Incorporated. It features two series-connected diodes in a compact SOT-23 surface-mount package. The device supports a maximum repetitive peak reverse voltage of 75 V and a continuous forward current of 300 mA DC. Key electrical parameters include a fast switching speed with a typical reverse recovery time of 4 ns, a forward voltage drop of 1.25 V at 150 mA, and low reverse leakage current of 2.5 µA at 75 V. This component is designed for general-purpose switching applications requiring reliable performance.

Feature Summary

• Fast switching speed suitable for high-frequency applications
• Compact surface-mount package ideal for automated insertion
• Dual diode configuration in a single package

Applications

• General purpose switching circuits
• Industrial control systems
• Signal rectification

Procurement Notes

Verify the specific suffix '-31' against the manufacturer's official documentation to confirm tape-and-reel specifications and packaging details. Ensure the component status is current, as some listings indicate this variant may be obsolete or superseded. Cross-reference the pinout and thermal characteristics with the latest datasheet to guarantee compatibility with existing board designs and assembly processes.

Selection Notes

Select this component when a dual diode solution is required in a minimal footprint. The SOT-23 package offers space efficiency compared to through-hole alternatives. Consider the 75 V reverse voltage rating and 300 mA current capacity to ensure adequate margins for the target circuit. Verify that the 4 ns switching speed meets the frequency requirements of the application.

Part Context

This part belongs to the BAV99 series of small signal switching diodes from Diodes Incorporated. The series is widely used in consumer electronics and industrial equipment for signal processing tasks. The BAV99-7-F-31 specifically denotes a version packaged in reels for automated manufacturing, distinguishing it from bulk-packaged variants.

Replacement Considerations

Check for direct substitutes such as the standard BAV99 or BAV99W if the reel packaging is not critical. Verify pin compatibility and electrical ratings before substituting with generic equivalents.
