Package

The MMBT2222A is typically packaged in a SOT-23 surface mount package. This compact, three-lead package is designed for low power applications and is suitable for automated assembly.

Pinout

The MMBT2222A is a widely used NPN bipolar junction transistor (BJT) in a TO-92 package. It has three pins:
1. Emitter (E): The terminal through which the charge carriers exit the transistor. It is typically connected to ground or the negative side of the circuit.
2. Base (B): The control terminal that regulates the flow of current between the collector and emitter. A small current at this pin controls a larger current between the collector and emitter.
3. Collector (C): The terminal through which the charge carriers enter the transistor. It is connected to the positive voltage supply and is responsible for the main current flow through the device.
The MMBT2222A is commonly used in switching and amplification applications due to its general-purpose nature, making it suitable for low to moderate power levels.
