■ High dv/dt and avalanche capabilities
■ Low input capacitance and gate charge
■ 100% avalanche tested
■ Low gate input resistance
■ Tight process control and high manufacturing
yields
Description
The MDmesh™ is a new revolutionary MOSFET
technology that associates the Multiple Drain
process with the Company’s PowerMESH™
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.
