MONOLITHIC DUAL NPN TRANSISTOR

The LS121 is a monolithic pair of NPN transistors mounted in a single TO-78 package. The monolithic dual chip design reduces parasitics and gives better performance while ensuring extremely tight matching. The LS121 is a direct replacement for discontinued Intersil IT121.
The hermetically sealed TO-78 is well suited for hi-rel and harsh environment applications.
