DESCRIPTION:
The MS2472 is a hermetically sealed, gold metallized, silicon
NPN power transistor. The MS2472 is designed for applications
requiring high peak power and low duty cycles such as IFF and
DME. The MS2472 is internal input/output matched resulting in
improved broadband performance and a low thermal resistance.
