MPSA13 Transistor Explained / Description:

MPSA14 is an NPN darlington transistor available in TO-92 and other small packages. Darlington transistor is a transistor that contains two transistors inside a single transistor package. These transistors are connected in a way which multiplies the input signal gain and increase it many times more as compare to the input gain but this process also increases the noise of the signal.

The maximum collector current of the transistor is 500mA and the maximum collector to emitter voltage is 30V.

The transistor is almost identical to MPSA13 and the only difference is their DC current gain as the MPSA13 DC current gain is 5000 and in MPSA14 it is 10,000.

Where We Can Use it & How to Use:

MPSA14 is designed for extremely high current gain requirements and can be used to drive a load with very low current. Other than that it can it can also be used for variety of high gain amplification purposes, but it is not limited to these uses and it can also be used in general purpose applications which falls under its specifications.

Applications:

Switching loads under 500mA with low current

Audio Preamplifier Applications

Audio Amplifier Stages

Sensor and Detector Circuits

Output of Microcontrollers and ICs

Output of Arduino, Raspberry Pi and Other Platforms

How to Safely Long Run in a Circuit:

For long life performance of MPSA14 in a circuit it is suggested to always use it 20% below from its max ratings. The maximum collector current of the transistor is 500mA therefore do not drive load of more than 400mA. The maximum collector to emitter voltage is 30V therefore do not drive load of more than 24V and always store of operate the transistor in temperature above -55 degree Celsius and below +150 degree Celsius.
