2SK3749 Datasheet, PDF (1/2 Pages) NEC – N-CHANNEL MOSFET FOR HIGH-SPEED SWITCHING
Product specification
2SK3749
DESCRIPTION
The 2SK3749 is an N-channel vertical MOS FET. Because
it can be driven by a voltage as low as 2.5 V and it is not
necessary to consider a drive current, this FET is ideal as an
actuator for low-current portable systems such as headphone
stereos and video cameras.

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.
