The SFF4393GW from Solid State Devices is an N-Channel Junction Field Effect Transistor (JFET) that is ideal for industrial and commercial applications. It has a gate-source voltage of -57 V and a drain saturation current of up to 30 mA. This junction field effect transistor (JFET) has a power dissipation of less than 1.8 W. It has a low ON resistance, ensuring efficient operation with minimal power loss. This transistor has a low capacitance and contributes to fast switching performance, enabling it to support high-speed analog circuits with negligible off-error. It is available in a surface-mount package that measures 0.350 x 0.130 mm.
