150 W – 50 V moisture resistant HF/VHF DMOS transistor. The SD2931-12MR is a gold metallized Nchannel MOS field-effect RF power transistor. Electrically identical to the standard SD2931 MOSFET, it is intended for use in 50 V DC large signal applications up to 230 MHz.
The SD2931-12MR is mechanically compatible with the SD2931 but offers better thermal capability (25% lower thermal resistance), representing the best-in-class in transistors for ISM applications, where reliability and ruggedness are critical factors. The SD2931-12MR benefits from the latest generation of environmentally designed packaging, ruggedized against cyclic high moisture operation and severe storage conditions.
