DESCRIPTION
The SD1542-04 is a hermetically sealed, gold me-
tallized, silicon NPN power transistor. The SD1542-
04 is designed for applications requiring high peak
power and low duty cycles such as IFF. The
SD1542-04 is packaged in a hermetic metal/ce-
ramic package with internal input matching, re-
sulting in improved broadband performance and
low thermal reistance.
