J112 Description
:
J112 is a J11x series high-performance N channel silicon FET or field effect transistor. Other transistors in this family include the JS111 and 112, which have similar functions but different specifications to meet specific needs. However, sample and hold applications, choppers, analog switching applications, commentators, current limiting, and other applications are the principal applications for these transistors.
There are also some advantages to using these transistors for specific applications, such as their suitability for high-speed switching, better frequency response, good accuracy, low insertion loss, and symmetrical feature, which allows the source and drain to be swapped. Aside from these advantages, they are also very inexpensive.
The transistor's maximum gate to source voltage is -35, maximum power dissipation is 625mW, and maximum continuous gate current is 50mA, according to its specifications. The TO-92 package and the tiny SOT-23 package are both available for these transistors.
