Overview
The BAV20 is a small signal silicon diode manufactured by onsemi, formerly Fairchild Semiconductor. It features a maximum repetitive reverse voltage of 200 V and an average rectified forward current rating of 200 mA. The device operates with a junction temperature up to 175 °C and supports storage temperatures ranging from -65 °C to +200 °C. Electrical characteristics include a maximum reverse current of 100 nA at 100 V reverse bias and a total capacitance of 5.0 pF measured at zero volts and 1.0 MHz frequency.
Feature Summary
- High breakdown voltage capability for general-purpose switching applications
- Low total capacitance suitable for high-frequency signal processing
- Robust thermal performance with extended operating junction temperature limits
Applications
- General purpose rectification in electronic circuits
- Signal clamping and protection stages
- High-speed switching operations
Procurement Notes
Verify the manufacturer origin as onsemi or legacy Fairchild Semiconductor stock. Confirm the package type matches the required DO-35 axial leaded format. Ensure the component status is active or full production rather than obsolete. Check datasheet revision history for any updated electrical parameters before final integration into the design.
Selection Notes
Select this component when a 200 V reverse voltage rating is required alongside standard signal diode speeds. Compare against BAV19 and BAV21 variants based on specific voltage thresholds. Consider the DO-35 package constraints for board space and mounting orientation. Evaluate thermal derating curves if ambient temperatures exceed standard operating ranges.
Part Context
This part belongs to the BAV19/20/21 series of small signal diodes designed for versatile electronic applications. The series offers differentiated reverse voltage ratings while maintaining consistent current handling and switching characteristics. These components are widely utilized in consumer electronics and industrial control systems requiring reliable signal management.
Replacement Considerations
BAV19 (120 V rating) and BAV21 (250 V rating) are direct functional substitutes within the same series. Verify that the replacement maintains the DO-35 package and identical pinout configuration.
