DESCRIPTION:
The MS2422 is a gold metallized silicon, NPN power transistor
designed for applications requiring high peak power and low duty
cycles such as IFF, DME, and TACAN. The MS2422 is designed
with internal input/output matching resulting in improved
broadband performance and low thermal resistance.
