MOS FIELD EFFECT TRANSISTOR
N-CHANNEL MOS FET
FOR HIGH-SPEED SWITCHING
2SK2109
The 2SK2109 is a N-channel MOS FET of a vertical type and
is a switching element that can be directly driven by the output of
an IC operating at 5 V.
This product has a low ON resistance and superb switching
characteristics and is ideal for driving the actuator, such as motors
and DC/DC converters.
FEATURES
• Low ON resistance
RDS(on) = 1.0 Ω MAX. @VGS = 4.0 V, ID = 0.3 A
• High switching speed
on + toff < 100 ns
t
• Low parasitic capacitance
