CS50N20 A8R
General Description
：
CS50N20 A8R, the silicon N-channel Enhanced
VDMOSFETs, is obtained by the self-aligned planar Technology
which reduce the conduction loss, improve switching
performance and enhance the avalanche energy. The transistor
can be used in various power switching circuit for system
miniaturization and higher efficiency. The package form is
TO-220AB, which accords with the RoHS standard.
