DESCRIPTION
The SD1534-08 is a gold metallized silicon, NPN
power transistor designed for applications requiring
high peak power and low duty cycles such as
IFF, DME and TACAN. The SD1534-08 is pack-
aged in the .280" input matched hermetic stripline
flange package resulting in improved broadband
performance and a low thermal resistance.
