DESCRIPTION
The 2SJ557A is a switching device which can be driven directly
by a 4 V power source.
The 2SJ557A 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.
Caution This product is electrostatic-sensitive device due to low ESD capability and should be handled with
caution for electrostatic discharge.
