Overview
The BAV21W-7-F is a surface mount switching diode manufactured by Diodes Incorporated in an SOD123 package. It features a peak repetitive reverse voltage of 200 V and a continuous forward current rating of 400 mA. The device dissipates up to 250 mW of power with a thermal resistance of 500 °C/W. Electrical characteristics include a maximum reverse recovery time of 50 ns, a total capacitance of 5.0 pF, and a forward voltage of 1.25 V at 200 mA. Operating temperatures range from -55°C to +150°C.
Feature Summary
- Fast switching speed suitable for general purpose applications
- High reverse breakdown voltage capability
- Totally lead-free and fully RoHS compliant construction
- Halogen and antimony free green device
Applications
- General purpose switching circuits
- Automotive applications requiring specific change control (BAV21WQ variant)
- Small signal processing tasks
Procurement Notes
Verify the exact part number against official Diodes Incorporated documentation to ensure correct specifications. Confirm compliance requirements such as RoHS and halogen-free status if mandated by your design standards. Check the datasheet for proper mounting and pad layout guidelines to ensure reliable performance. Ensure storage conditions align with moisture sensitivity level 1 per J-STD-020.
Selection Notes
Select this component when a high reverse voltage rating of 200 V is required in a compact SMD form factor. Consider the 50 ns reverse recovery time for moderate-speed switching needs. Evaluate the 250 mW power dissipation limit against your thermal management capabilities. Verify that the SOD123 package dimensions fit your PCB layout constraints.
Part Context
This component belongs to the BAV19W-BAV21W series of surface mount switching diodes. It shares similar mechanical and electrical characteristics with the BAV19W and BAV20W variants, differentiated primarily by their reverse voltage ratings. The series is designed for automated insertion and offers consistent performance across commercial grades.
Replacement Considerations
BAV20W-7-F: Lower reverse voltage rating of 150 V compared to 200 V. BAV19W-7-F: Lower reverse voltage rating of 100 V compared to 200 V. BAV21WQ-7-F: Automotive grade version with AEC-Q101 qualification and PPAP capability.
