LS122_TO-71

LS122 MONOLITHIC DUAL NPN TRANSISTOR Linear Systems replaces discontinued Intersil IT122 The LS122 is a monolithic pair of NPN transistors mounted in a single TO-71 package. The monolithic dual chip design reduces parasitics and gives better performance while ensuring extremely tight matching. The LS122 is a direct replacement for discontinued Intersil IT122. The hermetically sealed TO-71 is well suited for hi-rel and harsh environment applications. (See Packaging Information).
