The SD1541-09 is a gold metallized silicon NPN
planar transistor. The SD1541-09 is designedfor
applications requiring high peak and low duty cycles such as IFF. The SD1541-09 is packaged in
a metal/ceramic package with internal input matching, resulting in improved broadband performance
and a low thermal resistance.
