DESC RIPTION
The SD1528-08 is a gold metallized, silicon NPN
power transistor. The SD1528-08 is designed for
applications requiring high peak power and low
duty cycles such as IFF, DME and TACAN. The
SD1528-08 ispackaged in the .250” inputmatched
hermetic stripline flange package resulting in improved broadband performance and a low thermal
resistance.
