DATA SHEET
MOS FIELD EF2FESCTKTR2A1NS5IS8TOAR
N-CHANNEL MOSFET
FOR HIGH-SPEED SWITCHING
The 2SK2158A is an N-channel vertical type MOSFET featuring an operating voltage as low as 1.5 V. Because it can
be driven on a low voltage and it is not necessary to consider driving current, the 2SK2158A is suitable for use in low-
voltage portable systems such as headphone stereo sets and camcorders.
FEATURES
• Capable of drive gate with 1.5 V
PACKAGE DRAWING (Unit: mm)
• Because of high input impedance, there is no need to consider
driving current.
• Bias resistance can be omitted, enabling reduction in total
number of parts.

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.
