• Faster Switching
• Lower Leakage
• TO–258 Hermetic Package
StarMOS is a new generation of high voltage
N–Channel enhancement mode power MOSFETs.
This new technology minimises the JFET effect,
increases packing density and reduces the
on-resistance. StarMOS also achieves faster
switching speeds through optimised gate layout.
