SD2931-10 RF power transistor: HF/VHF/UHF N-channel power MOSFETs Datasheet production data Features Gold metallization Excellent thermal stability Common source configuration P = 150 W min. with 14 dB gain 175 MHz OUT Thermally enhanced packaging for lower junction temperatures 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 Figure 1. Pin connection signal applications up to 230 MHz. 4 1 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. 3 2 3.
