Precaution

Vth can be expressed as voltage between gate and source when low operating current value is ID = 100 mA for

this product. For normal switching operation, VGS (on) requires higher voltage than Vth and VGS (off) requires

lower voltage than Vth.

(relationship can be established as follows: VGS (off) < Vth < VGS (on) )

Please take this into consideration for using the device.

VGS recommended voltage of 4 V or higher to turn on this product.
