TO-126 is a type of semiconductor package for devices with three pins, such as transistors.[1] The package is rectangular with a hole in the middle to allow for easy mounting and/or heatsinking.

History and origin[edit]

The JEDEC TO-126 descriptor is derived from the original full name for the package: Transistor Outline Package, Case Style 126. In the updated JEDEC outline system, the package is numbered as TO-225AA.[2]
