DESC RIPT ION
The SD1541-01 is a hermetically sealed, gold metallized, silicon NPNpower transistor. TheSD154101 is designed for applications requiring high peak
power and low duty cycles such as DME. The
SD1541-01 is packaged in a hermetic metal/ceramic package with internal input/output matching,
resulting in improved broadband performance and
a low thermal resistance.
