BAS20 selection and design context
BAS20 is cataloged as a Switching Diode in the BAS20 family. Its recorded function is high-voltage high-speed silicon switching diode. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Reverse Voltage: 150 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Reverse Recovery Time: 50 ns max. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Diode Capacitance: 5 pF max. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Configuration: Single diode. Confirm the value and its datasheet test conditions for the exact ordering suffix.
Application and qualification considerations
When evaluating this protection device, confirm working voltage, clamping behavior, surge or ESD rating, capacitance, polarity and placement relative to the protected interface. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for BAS20
The recorded package is 3-lead SOT-23, the temperature range is -65°C to +150°C junction, and the lifecycle status is Production as of 2026-07-18.
