DESCRIPTION
Rugged glass package, using a high temperature alloyed
construction.
The SOD61AD2 is hermetically sealed and fatigue free as
coefficients of expansion of all used parts are matched.
The package is designed to be used in an insulating
medium such as resin, oil or SF6 gas.
The BYX135G is marked with a green cathode band on the
body.
