MOS FIELD EFFECT TRANSISTOR
2SK2158
N-CHANNEL MOS FET FOR HIGH-SPEED SWITCHING
The 2SK2158 is an N-channel vertical type MOS FET 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 2SK2158 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 • 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.
