Overview
The BAV21W-7-F is a surface mount switching diode manufactured by Diodes Incorporated in an SOD-123 package. It features a peak repetitive reverse voltage of 200 V and a forward continuous current rating of 400 mA. The device exhibits a maximum reverse recovery time of 50 ns and a total capacitance of 5.0 pF at 0 V reverse bias. Electrical characteristics include a forward voltage of 1.25 V at 200 mA and a peak reverse current of 15 µA at +100°C. Power dissipation is rated at 250 mW with a thermal resistance of 500 °C/W. Operating temperature ranges from -55°C to +150°C.
Feature Summary
- Fast switching speed suitable for general purpose applications
- High reverse breakdown voltage capability
- Surface mount package designed for automated insertion
Applications
- General purpose switching circuits
- Automotive electronics requiring specific change control (BAV21WQ variant)
- High reliability industrial applications
Procurement Notes
Verify the exact part number suffix, as 'BAV21W-7' differs from the documented 'BAV21W-7-F'. Confirm compliance requirements such as RoHS and Halogen-free status against the datasheet specifications. Ensure the ordering quantity aligns with the standard 3,000 units per tape and reel packaging format provided by the manufacturer.
Selection Notes
Select this component when a high reverse voltage rating of 200 V is required alongside fast switching performance. The SOD-123 case provides a compact footprint ideal for space-constrained designs. Consider the BAV21WQ variant if automotive qualification under AEC-Q101 standards and PPAP capability are necessary for the application.
Part Context
This component belongs to the BAV19W-BAV21W series of surface mount switching diodes produced by Diodes Incorporated. The series shares similar mechanical data and package dimensions while varying in reverse voltage ratings. The BAV21W represents the highest voltage option within this specific commercial lineup.
