DESCRIPTION
The 2SK3408 is a switching device which can be driven
directly by a 4.0 V power source.
The 2SK3408 features a low on-state resistance and excellent
switching characteristics, and is suitable for applications such
as power switch of dynamic clamp of relay and so on.

Remark The diode connected between the gate and source of the transistor serves as a protector against ESD.
When this device actually used, an additional protection circuit is externally required if a voltage exceeding
the rated voltage may be applied to this device.
