Description
M174
Epoxy sealed
The SD2931-10 is a gold metallized N-channel
MOS field-effect RF power transistor. Being
electrically identical to the standard SD2931
MOSFET, it is intended for use in 50 V dc large
signal applications up to 230 MHz.
Figure 1.
Pin connection
The SD2931-10 is mechanical compatible to the
SD2931 but offers in addition a better thermal
capability (25 % lower thermal resistance),
representing the best-in-class transistors for ISM
applications, where reliability and ruggedness are
critical factors.
