BAT54W

Single Diodes Overview

The BAT54W is a single silicon Schottky barrier diode manufactured by Taiwan Semiconductor Corporation. It is housed in an SOT-323 surface-mount package. The device supports a maximum repetitive peak reverse voltage of 30 V and a continuous forward current of 200 mA. Key electrical characteristics include a low forward voltage drop, typically around 650 mV at the rated current, and a low reverse leakage current of approximately 3 uA. The component operates within a temperature range of -55 °C to +150 °C and has a power dissipation rating of 200 mW.

Single Diodes Feature Summary

• Utilizes planar die technology for robust performance
• Features very small conduction losses due to low forward voltage
• Negligible switching losses suitable for high-speed applications
• Encapsulated in a compact SMD plastic package

Single Diodes Applications

• Ultra-high-speed switching circuits
• Line termination in communication systems
• Voltage clamping and protection
• Reverse polarity protection

Single Diodes Procurement Notes

Verify the specific manufacturer datasheet for the BAT54W produced by Taiwan Semiconductor Corporation. Confirm that the ordering suffix matches the exact pin configuration and electrical tolerances required for the design. Ensure compliance with RoHS directives and check for automotive qualification status if applicable to the target application environment.

Single Diodes Selection Notes

Select this component when a single Schottky diode with low forward voltage and fast switching speed is required in a minimal footprint. Compare the 30 V reverse voltage rating against circuit peaks. Consider the SOT-323 package dimensions for PCB layout constraints. Evaluate thermal management needs based on the 200 mW power dissipation limit under expected operating conditions.

Single Diodes Part Context

The BAT54W belongs to the family of small signal Schottky diodes designed for general-purpose rectification and switching. These devices are characterized by their low profile and suitability for automated surface-mount assembly. They serve as alternatives to standard PN junction diodes where reduced voltage drop and faster recovery times are critical for system efficiency.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers' BAT54W equivalents such as those from Diotec, Vishay, or Nexperia. Verify that substitute parts maintain identical pinout configurations and meet the same 30 V and 200 mA ratings. Check for any differences in forward voltage specifications or packaging codes.
