DESCRIPTION
The SD1538-08 is a gold metallized, silicon NPN
power transistor. The SD1538-08 is designed for
applications requiring high peak power and low
duty cycles such as IFF, DME and TACAN. The
SD1538-08 is packaged in a metal/ceramic pack-
age with internal input/output matching, resulting
in improved broadband performance and low ther-
mal resistance.
