DESCRIPTION
PACKAGE DRAWING (Unit : mm)
The µPA2451 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 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.
