BAV20W

Overview

The BAV20W is a silicon signal diode manufactured by Taiwan Semiconductor Corporation, encapsulated in a SOD-123 plastic package. It is designed for general-purpose switching applications with a maximum repetitive peak reverse voltage of 250 V and an average forward rectified current rating of 200 mA. The device features a low forward voltage drop and fast switching characteristics suitable for high-speed digital circuits.

Feature Summary

• Hermetically sealed planar technology construction
• Fast switching speed capability
• Low forward voltage drop characteristic

Applications

• General purpose switching in industrial equipment
• Digital voltmeter input stages
• Oscilloscope signal conditioning

Procurement Notes

Verify the specific suffix or tape-and-reel configuration required for automated assembly. Confirm RoHS compliance status and lead-free certification details directly with the manufacturer or authorized distributor before finalizing procurement specifications.

Selection Notes

Select this component when a robust 250 V reverse voltage rating is required in a compact surface-mount footprint. Ensure the application demands standard switching speeds rather than ultra-fast recovery variants. Verify thermal management requirements against the specified junction temperature limits.

Part Context

This part belongs to the BAV series of small-signal switching diodes. It shares functional similarities with the BAV21W but offers a higher reverse voltage rating. The SOD-123 package provides a balance between power handling and board space efficiency compared to larger through-hole alternatives.
