BDW93C Basics
The BDW93C is a silicon epitaxial-base NPN power transistor configured in a monolithic Darlington arrangement, housed in a JEDEC TO-220 plastic package. This transistor is designed for power linear and switching applications, offering excellent current amplification characteristics suitable for high-power circuit requirements. Additionally, its complementary PNP transistor is the BDW94C, with the BDW94B also available as a PNP option, providing designers with various choices to meet different circuit needs.
BDW93C Pinout
The BDW93C typically has a TO-220 package with the following pinout:
Collector (C): The collector pin is used to connect the power supply or load.
Base (B): The base pin is used for controlling the transistor and is connected to the input signal.
Emitter (E): The emitter pin is connected to the ground or the negative side of the circuit.

How to Use BDW93C?
When using the BDW93C, start by connecting it correctly according to its pinout. The collector (C) is usually connected to the load, the emitter (E) to ground or the negative terminal, and the base (B) to the control signal through a suitable resistor. Make sure the connections are secure to avoid poor contact.
After the wiring is done, check the power supply voltage and current to ensure they are within the safe operating range of the BDW93C. Power on the circuit and monitor the transistor's behavior. If you notice any overheating or unusual behavior, turn off the power immediately to prevent damage.
Finally, adjust the base control signal according to your needs. For example, when driving a motor, you can control the motor’s start, stop, or speed by varying the base current. By following these steps, the BDW93C can effectively function in your circuit.
