Overview
The BAV19WS-HG3-18 is a general-purpose switching diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage of 100 V and an average rectified forward current of 250 mA. The device is housed in a surface-mount SOD-323 package. Key electrical specifications include a peak forward surge current capability of 1 A, a maximum reverse leakage current of 100 nA, and a typical forward voltage drop of 1.25 V at rated current. The component operates within a junction temperature range up to 150°C and exhibits a maximum reverse capacitance of 500 fF.
Feature Summary
- Surface-mount construction in a compact SOD-323 package for automated assembly
- High-speed switching characteristics with low reverse capacitance
- Lead-free and RoHS compliant manufacturing process
Applications
- General purpose signal switching circuits
- Protection against reverse polarity in low-voltage systems
- Clamping and clamping applications in consumer electronics
Procurement Notes
Verify the specific suffix HG3 indicates lead-free and halogen-free compliance when sourcing. Confirm the SOD-323 tape and reel packaging format matches your pick-and-place equipment requirements. Ensure the 100 V reverse voltage rating meets the peak inverse voltage demands of the target circuit design before finalizing procurement.
Selection Notes
Select this component for designs requiring a small footprint with standard switching performance. The 250 mA current rating suits low-power signal paths rather than high-current power handling. Consider the 100 V breakdown voltage as the upper limit for reverse bias conditions in the application environment.
Part Context
This part belongs to the BAV19 series of small-signal switching diodes from Vishay. It serves as a surface-mount alternative to through-hole variants, maintaining similar electrical characteristics while enabling higher density PCB layouts. The HG3 suffix denotes environmental compliance standards required for modern electronic manufacturing.
