The part number " BAT54C " refers to a specific Schottky diode made by Nexperia. The BAT54C is typically used in low-voltage, high-speed switching applications due to its small package and low forward voltage.
Pin Function Specifications and Circuit Principle:
The BAT54C is commonly available in the SOT-23 package, which typically has 3 pins. This package is a su RF ace-mount component commonly used in electronics.
Pin Function Specifications (SOT-23 Package with 3 Pins): Pin Number Pin Name Pin Function Description 1 Anode The anode is connected to the input side of the Schottky diode. In the BAT54C, this is the pin where the current enters the diode. 2 Cathode The cathode is connected to the output side of the diode. This is where the current exits the diode. 3 Anode The second anode pin is used for connecting to the second Schottky diode in the BAT54C package. Both diodes share the same cathode pin. Circuit Principle:The BAT54C is designed for use in high-speed switching and low-voltage applications. The primary circuit principle relies on the low forward voltage drop of the Schottky diode, which minimizes power loss and enhances switching speed. In typical applications, it is used for protecting circuits from reverse polarity, as well as in rectifying circuits.
BAT54C Pin Function List (Full 3-Pin Description)
Since the BAT54C comes in a 3-pin SOT-23 package, here’s the detailed description for each pin:
Pin 1 (Anode 1): This is the first anode pin of the diode. It connects to the anode of the first diode in the BAT54C Schottky diode. The current flows through this pin from the circuit into the diode when the device is in forward bias.
Pin 2 (Cathode): This is the shared cathode pin for both diodes in the BAT54C package. When the diode is in forward bias, the current will exit the diode from this pin. The cathode is connected to the output side of the circuit.
Pin 3 (Anode 2): This is the second anode pin, connected to the second diode inside the package. The BAT54C features two diodes in a single package, so both anode pins are provided for separate connections in a circuit, but they share the same cathode pin.
