TO-126 Package

                                                  

The TO-126 is a type of plastic-molded 'transistor outline' package commonly used for housing discrete devices such as transistors and thyristors.

    

The TO-126, which normally has a metal plate at the back, is designed to handle more power than smaller plastic-molded TO- packages. Its body has a hole so it can be easily attached to a metal heat sink and allow it to dissipate heat at a faster rate.

  

Since it is most often used in transistor packaging, the TO-126 usually has three leads, all of which protrude from the bottom of the package.  

  

The TO-126 package combines the advantages of an ordinary plastic-molded TO package (low manufacturing cost and small size) with the good power handling capability of metal can packages.
