The MPSA92 and MPSA116 are both Bipolar Junction Transistors (BJT) categorized as one of the many type of semiconductor devices. This section will discuss the application field, working principle and package information of the MPSA92 and MSPA116 BJTs.

MPSA92 and MPSA116 characteristics

The MPSA92 and MPSA116 are silicon NPN types, medium power transistors. They have current gain bandwidth product of 500MHz and DC current gain grade of 5. Both transistors also have a collector emitter breakdown voltage of -45V, a collector base breakdown voltage of -65V and an emitter base breakdown voltage of -5V. Their collector and emitter power dissipation ratings are both 350mW and their maximum collector current ratings are 2A each.

MPSA92 and MPSA116 package

The MPSA92 and MPSA116 are available in different packages. The MPSA92 comes in a TO-92 package, while the MPSA116 comes in both TO-92 and TO-126 packages. The differences between these packages are the pin configurations and size. The TO-92 package typically has three leads (base, collector and emitter) and has a smaller package size compared to the TO-126. The TO-126 package has a similar configuration to the TO-92 but usually has four leads (an extra emitter pin is present), thus having a larger package size.

MPSA92 and MPSA116 application field

The MPSA92 and MPSA116 can be used for various applications such as audio amplifiers, switching circuits and oscillators. They are ideal for low to medium power applications due to their low power dissipation ratings. They are also suitable for switching and amplifier circuits due to their current gain bandwidth product. One of their popular applications is in the design of low power amplifier circuits. They can be used to amplify small signals such as audio signals. The MPSA92 and MPSA116 are also used in oscillator circuits because of their high current gain bandwidth product. These oscillators can be used to generate signals of different frequency ranges.

MPSA92 and MPSA116 working principle

The MPSA92 and MPSA116 are Bipolar Junction Transistors (BJTs) composed of three terminals: the collector, the base and the emitter. It is an active device, meaning it can control electric current depending on its input. Typically, the collector is connected to the supply voltage (V cc ) or the drain, the base is connected to the signal source or controller and the emitter is connected to the ground or the source. To understand how it works, a simplified model of the BJT is used in which its operation can be divided into three regions.
The active or linear region is when the base current (I B ) is slightly greater than the emitter current (I E ). When this happens, an amplification factor (h FE ) is formed, allowing the base current (I B ) to control the additional current (I C ) entering the collector. The saturation region is when the voltage applied between the collector and the emitter (V CE ) is held at zero, but with a large base current (I B ) thus causing an additional large collector current (I C ). Lastly, the Cutoff region is when there is no base current present (I B = 0) and the voltage at the collector and emitter is at its maximum (V CE ). This results in zero current flow from the collector to the emitter (I C = 0).

Conclusion

The MPSA92 and MPSA116 are two types of Bipolar Junction Transistors (BJTs). They are popularly used in low and medium power applications such as switching circuits, audio amplifiers, and oscillator circuits. They are characterized by their current gain bandwidth product of 500MHz, with a DC current gain grade of 5. Additionally, their Collector-Emitter voltage rating for the MPSA92 is -45V and for the MPSA116 is -65V. The MPSA92 and MPSA116 are available in different packages (TO-92 and TO-126).
