DESCRIPTION
The 2SJ557 is a switching device which can be driven directly
by a 4 V power source.
The 2SJ557 features a low on-state resistance and excellent
switching characteristics, and is suitable for applications such
as power switch of portable machine 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.
