BAT54C-G

Overview

The BAT54C-G is a surface mount Schottky diode manufactured by Comchip Technology, housed in an SOT-23 package. It features a dual common cathode configuration with two internal elements. The device supports a maximum DC forward current of 200 mA and a repetitive peak reverse voltage of 30 V. Key electrical characteristics include a maximum reverse leakage current of 2.0 mA at 25 V and a typical total capacitance of 7.6 pF. The component operates within a junction temperature range up to 125°C and a storage temperature range from -55°C to +150°C.

Feature Summary

• Low turn-on voltage for efficient signal rectification
• Fast switching capability suitable for high-frequency applications
• PN junction guard ring structure provides transient and ESD protection

Applications

• Free-wheeling and polarity protection diodes in compact circuits
• Low voltage and high frequency rectification
• Signal processing in surface mount assemblies

Procurement Notes

Verify the datasheet confirms the specific BAT54C-G variant matches your circuit requirements. Ensure the RoHS compliant suffix designation aligns with environmental regulations. Confirm the SOT-23 package dimensions fit your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when low forward voltage drop and fast recovery are critical. The dual common cathode design allows for efficient use of board space compared to discrete single diodes. Verify that the 200 mA continuous current rating meets the load requirements of the specific application environment.

Part Context

This part belongs to the BAT54 series of surface mount Schottky diodes produced by Comchip Technology. The series includes variants such as BAT54A-G and BAT54S-GBAT54C-G, all sharing the SOT-23 footprint. The product line emphasizes small size and reliability for modern electronic assembly processes.

Replacement Considerations

BAT54CHY serves as a confirmed substitute with identical pinout and package specifications.
