Transistor Outline (TO) Package Types

               

The transistor outline (TO) package family consists of many types of packaging solutions for transistors and similar discrete devices as well as simple IC's with low pin counts.  The structures of TO packages vary widely, from expensive metal can enclosures to low-cost plastic-molded package bodies (see Table 1 below).
