BAV199

Overview

The BAV199 is a dual surface mount low leakage diode manufactured by Diodes Incorporated. It features two silicon signal diodes connected in series within an SOT23 package. The device supports a peak repetitive reverse voltage of 85V and a continuous forward current of 160mA per diode. Electrical characteristics include a maximum reverse leakage current of 5nA at 75V, a typical total capacitance of 2pF, and a reverse recovery time of 3µs. Operating temperatures range from -55°C to +150°C with a power dissipation rating of 250mW.

Feature Summary

• Dual diode configuration with internal series connection for compact circuit integration
• Very low leakage current suitable for high-precision applications
• Totally lead-free and fully RoHS compliant construction
• Automotive qualified variant (BAV199Q) available with AEC-Q101 certification

Applications

• Low-leakage current applications in surface mounted circuits
• High precision instrumentation requiring minimal bias current
• Automotive electronics requiring specific change control standards

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard BAV199-7-F indicates a tape and reel quantity of 3000 units. Automotive grade variants carry the Q suffix (e.g., BAV199Q-7-F). Confirm date codes if halogen-free green molding compound is required, as older stock may differ. Ensure compatibility with IATF16949 certified facilities if automotive PPAP capability is necessary.

Selection Notes

Select this component for designs requiring dual series-connected diodes in a small footprint. The low leakage specification makes it appropriate for sensitive analog front ends or high-impedance switching circuits. Consider the BAV199Q variant if the application demands automotive reliability standards and traceability. Verify thermal management requirements against the 500 °C/W junction-to-ambient resistance.

Part Context

This part belongs to the BAV199 family of dual surface mount low leakage diodes produced by Diodes Incorporated. It utilizes a molded plastic SOT23 package with matte tin finish terminals. The device is designed for automated insertion and offers a compact solution for replacing discrete dual-diode arrangements in space-constrained printed circuit board layouts.

Replacement Considerations

Direct substitutes include other dual series-connected low leakage diodes in SOT23 packages such as the BAS21 or BAV99 series, though electrical parameters like leakage and speed may vary. Verify pinout compatibility and ensure replacement parts meet the same reverse voltage and current ratings.
