Product description: MOSFET Power Switch - 12 V / 10 A switch with transistor - PSMN7R0-100BS - SparkFun SPX-19799
MOSFET Power Switch is a module from SparkFun , which has been equipped with the PSMN7R0-100BS system. It functions as a digital switch , it is controlled by pins with a voltage of 3.3 V. The maximum supported voltage is 12 V, and the maximum current is 10 A. The module also has outputs in the form of solder pads and a screw connection. It is used wherever it is necessary to control devices with higher current consumption than allowed by the control system, e.g. a microcontroller.

Differences between unipolar and bipolar transistor
Bipolar transistors are distinguished by the fact that as the temperature increases, the collector current also increases, which may prevent the direct connection of several transistors in parallel.
MOSFET transistors (unipolar) due to their technical construction are very sensitive to electrostatic charges. The maximum voltage UGS in most models is usually around 20 V, which means that it is easy to exceed it without any awareness, even by touching the transistor in a completely dry room.
More information about the unipolar transistor can be found in our article - Unipolar transistors (MOSFET) - what is it? How it works? Explanation for beginners.
