MPSA13 Brief Intro

The MPSA13 is a NPN Darlington Transistor, meaning it has two NPN transistors inside a single package. The Emitter of the first transistor is connected to the base of the second transistor and both the collector pins are clubbed together as shown in the pinouts image.

This property enables the transistor to have very high gain, like here the MPSA13 has a gain of 5000. This high gain can be useful when designing Audio amplifier circuits. The transistor is also used with Sensors and display drivers since a very small current into the base of the transistor will trigger the transistor making it to conduct.
