Precaution

Let Vth be the voltage applied between gate and source that causes the drain current (ID) to be low (0.1mA for the

SSM3K44FS). Then, for normal switching operation, VGS(on) must be higher than Vth, and VGS(off) must be lower than

Vth. This relationship can be expressed as: VGS(off) < Vth < VGS(on).

Take this into consideration when using the device
