Pinout

The MJ15003 is a high-power NPN transistor commonly used in audio amplifier and linear power supply applications. It features a total of 3 pins. Here are the pin assignments and their functions:
1. Collector (C): This is the output terminal where the load is connected. It collects the current from the emitter and is responsible for delivering power to the load.

2. Base (B): This is the control terminal that modulates the transistor's operation. A small current applied to the base allows a larger current to flow from the collector to the emitter, effectively amplifying the signal.
3. Emitter (E): This terminal emits current to the ground or supply. It is the output side of the transistor, where the current exits to the circuit.
The MJ15003 is known for its high voltage and current ratings, making it suitable for demanding applications.
