The MDmesh is a new revolutionary Power 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 competitor’s products.
