Product overview

Description

The SD2943 is a gold metallized N-channel MOS field-effect RF power transistor. It is used for 50 V DC large signal applications up to 150 MHz. The SD2943 offers a 20% higher power saturation than the SD2933, and is ideal for ISM applications where reliability and ruggedness are critical factors.
