BAT43W

Single Diodes Overview

The BAT43W is a Schottky barrier diode manufactured by Taiwan Semiconductor Corporation, housed in an SOD-123 surface-mount package. It features a maximum DC reverse voltage of 30 V and an average rectified forward current of 200 mA. The device exhibits a forward voltage of 1 V at 200 mA and a reverse leakage current of 500 nA at 25 V. Key electrical characteristics include a reverse recovery time of 5 ns and a capacitance of 10 pF at 1 V and 1 MHz. The junction operating temperature range spans from -55°C to 125°C.

Single Diodes Feature Summary

• Low forward voltage drop for improved efficiency
• Surface mount device type for automated assembly

Single Diodes Applications

• High-speed switching circuits
• Power supply rectification
• Clamping applications

Single Diodes Procurement Notes

Verify the manufacturer designation as Taiwan Semiconductor Corporation when sourcing this component. Confirm the specific suffix (e.g., RHG) if required for lead-free plating or tape-and-reel packaging specifications. Ensure compliance with RoHS directives and check for automotive qualification status, which is typically not applicable for this general-purpose signal diode variant.

Single Diodes Selection Notes

Select the BAT43W for applications requiring fast switching speeds and low forward voltage loss in compact designs. The SOD-123 package offers a balance of thermal performance and board space efficiency. Consider the 30 V reverse voltage rating to ensure adequate margin against transient spikes in the target circuit environment.

Single Diodes Part Context

This component belongs to the BAT43W series of small-signal Schottky diodes. It is functionally similar to other 30V, 200mA Schottky devices but is distinguished by its specific thermal and electrical characteristics defined by Taiwan Semiconductor. The series is designed for general-purpose high-speed switching and rectification tasks in consumer and industrial electronics.
