BAV20WS-G3-18

Overview

The BAV20WS-G3-18 is a small-signal switching diode manufactured by Vishay General Semiconductor - Diodes Division. It utilizes planar technology and is housed in an SOD-323 surface-mount package. The device features a maximum DC reverse voltage of 150 V and a continuous forward current rating of 250 mA. Key electrical parameters include a peak reverse voltage of 200 V, a repetitive peak forward current of 625 mA, and a maximum reverse leakage current of 100 nA at 150 V. The component exhibits a fast recovery time of 50 ns and a typical junction capacitance of 1.5 pF at 0 V and 1 MHz. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Hermetically sealed leaded glass construction for environmental stability
• Fast switching capability with a maximum recovery time of 50 ns
• High thermal stability supporting operation up to 150°C junction temperature

Applications

• General purpose switching in industrial equipment
• Input stages for digital voltmeters
• Video output stages in color television sets

Procurement Notes

Verify the specific suffix G3-18 against the manufacturer's latest datasheet to confirm RoHS compliance and packaging configuration. Ensure the ordering part number matches the required SOD-323 variant. Cross-reference the AEC-Q101 qualification status if automotive reliability is required for the design. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this component when a hermetically sealed planar diode with 50 ns switching speed is required in an SOD-323 footprint. It serves as a suitable replacement for standard BAV20 series devices where higher reliability or specific package constraints exist. Consider the 150 V reverse voltage rating and 250 mA forward current limits during circuit design to ensure safe operating area compliance.

Part Context

The BAV20WS-G3-18 belongs to the BAV20/BAV21 family of general-purpose switching diodes. These components are fabricated using planar technology and are distinguished by their hermetically sealed leaded glass packages. While many modern variants use plastic encapsulation, this specific WS designation indicates the glass-sealed construction, offering distinct advantages in harsh environments compared to standard plastic equivalents.

Replacement Considerations

Direct substitutes include other BAV20 series variants such as BAV20W-E3-18 or BAV20WS-HE3-08, provided the package and sealing type match the design requirements. Verify that alternative parts maintain the 50 ns recovery time and 150 V reverse voltage specifications.
