BAT54C

The BAT54C is a Schottky barrier diode manufactured by Multicomp, designed for various electronic applications requiring fast switching and low forward voltage drop. Here’s a detailed description of its key features and specifications:

General Description:

The BAT54C is a small-signal Schottky diode that is particularly well-suited for high-speed switching applications. It is commonly used in RF applications, signal detection, and as a rectifier in low-voltage power supplies. The diode is known for its low forward voltage drop and fast recovery time, making it ideal for applications where efficiency is critical.

Package:

The BAT54C is typically housed in a compact SOT-23 package, which is a surface-mount technology (SMT) package. This small form factor allows for efficient use of PCB space, making it suitable for modern electronic designs where size is a constraint.

Electrical Characteristics:

• Forward Voltage Drop (Vf): The forward voltage drop is typically around 0.3V at a forward current of 1mA, which is significantly lower than that of standard silicon diodes. This characteristic helps in reducing power loss in circuits.
• Reverse Voltage (Vr): The maximum reverse voltage rating is usually around 30V, allowing it to handle a variety of applications without risk of breakdown.
• Forward Current (If): The BAT54C can handle a forward current of up to 200mA, making it suitable for low to moderate current applications.
• Reverse Leakage Current (Ir): The reverse leakage current is low, typically in the range of microamperes, which is advantageous for battery-operated devices where power conservation is essential.

Performance:

The BAT54C exhibits excellent switching performance, with a fast recovery time that allows it to operate efficiently in high-frequency applications. Its low capacitance also contributes to its suitability for RF applications, where signal integrity is paramount.

Applications:

• Signal Demodulation: Used in RF applications for demodulating signals.
• Rectification: Acts as a rectifier in low-voltage power supplies.
• Clamping: Can be used for clamping applications to protect sensitive components from voltage spikes.
• Mixers: Utilized in mixer circuits for frequency conversion.

Conclusion:

The BAT54C from Multicomp is a versatile Schottky diode that combines low forward voltage drop, fast switching speed, and compact packaging, making it an excellent choice for a wide range of electronic applications. Its reliability and efficiency make it a popular component among engineers and designers in the field of electronics.
