Working Principle of MJD112-TP

MJD112-TP transistors are made up of two NPN transistors connected together within the same package. This type of transistor is known as a bipolar junction transistor, meaning that the current can flow both directions depending on the voltage applied to the gate. The two NPN transistors within the MJD112-TP are separated by a thin dielectric layer and connected together in the form of an Emitter-Collector-Emitter (ECE) structure. The left side of the transistor is the base and contains five terminals, while the right side is the collector and contains four terminals. When an electrical impulse is sent to the base, it is concentrated and amplified through the two transistors. This process is known as current gain, and it allows the MJD112-TP to switch between high and low voltage levels. The NPN transistors can be used independently, allowing the designer to switch between different voltage and current levels. This makes the MJD112-TP an ideal choice for those looking to create power amplifiers, power supply circuits, application circuits, multi-stage switching and high-voltage circuits.
