Pin Function Specifications and Circuit Principle Instructions

1. Package Type: The BAT54XV2T1G comes in a SOT-23 package. This package is a small, surface-mount type, commonly used for low-power diodes and transistor s. 2. Pin Count and Function: The BAT54XV2T1G comes with a 3-pin configuration. Below is a detailed explanation of the pins' functions and their corresponding roles: Pin Pin Name Description Pin 1 Anode (A) The anode of the Schottky diode, where the input signal or positive voltage is applied. Pin 2 Cathode (K) The cathode of the Schottky diode, where the output signal or negative voltage is collected. Pin 3 Cathode (K) This is the second cathode pin, for a dual Schottky diode configuration (this device contains two diodes in one package). It is also connected to the same negative side of the circuit as Pin 2. 3. Detailed Pin Function Description:

Pin 1 (Anode): This pin is where the current enters the Schottky diode, which is used for rectification or protection in electronic circuits. The anode is typically connected to the more positive voltage in a circuit.

Pin 2 & Pin 3 (Cathode): These two pins are the cathodes of the Schottky diodes inside the BAT54XV2T1G. Both cathodes are connected to the same voltage potential and are used to output current in the reverse direction.

4. Circuit Principle: The BAT54XV2T1G is a Schottky diode, meaning it uses a metal-semiconductor junction to allow current to flow in only one direction with minimal voltage drop (typically around 0.2 to 0.3 volts). When used in circuits, the diodes provide fast switching and low forward voltage drop, making them ideal for applications such as rectification, voltage clamping, or RF circuits. The two diodes within the device are often used for different parts of a circuit, such as rectifying positive and negative voltages in a dual-voltage application.
