BAV19WS

Overview

The BAV19WS is a single silicon signal diode manufactured by SMC Diode Solutions, designed for surface-mount applications. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current of 200 mA. The device exhibits a typical reverse recovery time of 50 ns and a low leakage current of 200 nA at 100 V. Operating within a junction temperature range of -65°C to 150°C, it utilizes the SOD-323 (SC-90) package.

Feature Summary

• Glass passivated chip junction for enhanced stability
• Fast reverse recovery characteristics suitable for switching
• Designed for automated placement in surface-mount processes

Applications

• General purpose signal switching circuits
• High-speed rectification in compact designs
• Clamping and protection in consumer electronics

Procurement Notes

Verify the specific manufacturer designation when sourcing, as multiple vendors produce the BAV19WS variant. Confirm that the component meets RoHS 2011/65/EU directives if environmental compliance is required. Ensure the SOD-323 footprint matches the target PCB layout. Cross-reference datasheets from different suppliers to confirm identical pinout and electrical limits before integration.

Selection Notes

Select this component for applications requiring a small form factor with moderate reverse voltage tolerance. The 100 V rating distinguishes it from lower-voltage counterparts like the BAV170 series. Consider the 200 mA current limit for load requirements. The SOD-323 package offers a balance between thermal performance and space efficiency compared to larger through-hole options.

Part Context

This part belongs to the BAV19W/BAV20W/BAV21W family of fast-switching diodes. While sharing similar packaging and basic switching speeds, the BAV19WS is specifically rated for 100 V reverse voltage, whereas variants like the BAV21WS support up to 200 V. This differentiation allows designers to optimize cost and performance based on circuit voltage requirements.
