Description
The MDmeshTM is a new revolutionary Power Internal schematic diagram
MOSFET technology that associates the multiple
drain process with the company's PowerMESHTM
horizontal layout. The resulting product has an
outstanding low on-resistance, impressively high
dv/dt and excellent avalanche characteristics. The
adoption of the company's proprietary strip
technique yields overall dynamic performance
that is significantly better than that of similar
competition's products.
