DESCRIPTION

Rugged glass package, using a high temperature alloyed construction. This package 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. Fig.1 Simplified outline (SOD83A) and symbol. The cathode is marked by a black band on the body. handbook, halfpage MSA480 ak /#03 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134). SYMBOL PARAMETER CONDITIONS MIN.
