What is a General Purpose Transistor?

A transistor is a semiconductor with a solid and non-moving part to pass a charge. It can amplify and switch electrical power and electronic signals. Transistors are made of semiconductor material with three or more terminals used to connect to an external circuit. By applying a current or a voltage to one of the pairs of the terminals, there is a change in current through another pair of terminals. Transistors can amplify a signal because output power can be higher than input power.

Types of General Purpose Transistors

There are many different kinds of general purpose transistors and at Future Electronics we stock many of the most common types categorized by Polarity, Total Power Dissipation, Collector Current @ 100C, Packaging type and Maximum CE Voltage. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for Maximum CE Voltage are 40 V, 45 V and 60 V. We also carry general purpose transistors with Maximum CE Voltage as high as 800 V. Total Power Dissipation can be between 0.5 mW and 250 W, with the most common general purpose transistors having a Total Power Dissipation of 625 mW.
