1. H = HIGH voltage level
h = HIGH voltage level one set-up time prior to the
HIGH-to-LOW LE transition
L = LOW voltage level
I = LOW voltage level one set-up time prior to the
HIGH-to-LOW LE transition
X = don’t care
Z = high impedance OFF-state

KF16N25D

MOSFET의 기능은 N Channel MOS Field effect transistor입니다. This planar stripe MOSFET has better characteristics, such as fast switching time, low on resistance, low gate charge and excellent avalanche characteristics. It is mainly suitable for DC/DC Converters and switching mode power supplies.( Vdss=250V, Id=13A )
