DESCRIPTION
The
PA1820 is a switching device which can be
driven directly by a 2.5 V power source.
This device features a low on-state resistance and
excellent switching characteristics, and is suitable for
applications such as DC/DC Converters and power
management of notebook computers 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.
