The TO-92 is a widely used style of semiconductor package mainly used for transistors. The case is often made of epoxy or plastic, and offers compact size at a very low cost.

Comparison between the E-Line/Miniplast package and the TO-92 package
The TO-220 is a style of electronic package used for high-powered, through-hole components with 0.1 inches pin spacing. The "TO" designation stands for "transistor outline". TO-220 packages have three
TO-92
…this style of case is the lack of heat sinking. Transistors and ICs of these types cannot handle as much power as higher-power equivalents, such as the TO-220, and can burn out quickly if they dissipate excessive power. There is no standard pinout for the TO-92. The American BJTs use the E-B-C pinout while…
