CS90N045 A3
General Description
：
CS90N045
A3,
the
silicon
N-channel
Enhanced
VDMOSFETs, is obtained by the high density Trench
technology which reduce the conduction loss, improve switching
performance and enhance the avalanche energy. This device is
suitable for use as a load switch and PWM applications. The
package form is TO-251, which accords with the RoHS standard.
