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.
