Transistor Pinouts ( Beavis )

Transistor Pinouts and General Data

All pin orientations are shown as you are looking at the bottom of the transistor. Different manufacturers may sometimes use different pinout configurations. Always check before you solder. Or better yet, use sockets. Figures for hFE are shown as an average of values from various manufacturers of a said type, where applicable. Check your specific manufacturer's datasheet for actual rated hFE, or better yet, measure it to be sure. Case styles shown are for the most common types. However, various transistors are available in different case styles, which may affect pinout. For example, the 2N2222 type typically comes in a metal TO-18 case, but is also available in plastic TO-92 cases.
