BAT43W

Single Diodes Overview

The BAT43W is a Schottky barrier rectifier manufactured by SMC Diode Solutions, housed in the surface-mount SOD-123 package. It features a maximum DC reverse voltage (Vr) of 30 V and an average forward rectified current (Io) of 200 mA. The device exhibits a typical forward voltage (Vf) of 1 V at 200 mA and a low reverse leakage current of 500 nA at 25 V. Its junction capacitance is specified as 10 pF at 1 V and 1 MHz. The component operates within a junction temperature range of -55°C to 125°C.

Single Diodes Procurement Notes

Verify the manufacturer designation on the datasheet, as the BAT43W part number is also utilized by Diodes Incorporated. Confirm that the specific batch corresponds to SMC Diode Solutions production when sourcing from distributors. Ensure the ordering suffix matches the required tape-and-reel or cut-tape configuration for your manufacturing process. Cross-reference the DigiKey part number 1655-BAT43W-ND for accurate identification.

Single Diodes Selection Notes

Select this component for applications requiring fast switching speeds and low forward voltage in compact surface-mount designs. The SOD-123 form factor suits space-constrained PCB layouts. Consider the 30 V reverse voltage rating to ensure adequate margin for the operating circuit. Evaluate the 200 mA current limit against peak load requirements to prevent thermal overstress during continuous operation.

Single Diodes Part Context

The BAT43W belongs to the category of small-signal Schottky diodes designed for efficient power conversion and signal processing. Manufactured by SMC Diode Solutions, it complements their broader portfolio of discrete semiconductors. The device utilizes standard silicon planar technology optimized for reliability in consumer and industrial electronics environments.

Single Diodes Replacement Considerations

BAT43W-7 is a functionally equivalent part from Diodes Incorporated. Verify pinout compatibility and package dimensions before substitution. Check if the alternative manufacturer's Vf and leakage specifications meet the original design constraints.
