Darlington transistor
The schematic shows the Darlington transistor, they are been at two types PNP and NPN, MPSA13 is an NPN Darlington transistor device.
The connection of the Darlington transistor is connecting two NPN or PNP transistors back to back, which is the output of one transistor towards another transistor input.
The Darlington pair transistor had a higher gain than the normal transistors, due to the back-to-back connection between two transistors.
MPSA13 transistor package
The MPSA13 Darlington transistors have a TO-92 package, most of the time TO-92 is used for general-purpose devices.
The TO-92 package is made with epoxy/plastic material for heat resistance and compactness as an electronic component.
The less-weight TO-92 package will support the MPSA13 transistor by making small circuits like touch sensors.
