Description
The new SuperMESH™ series of Power MOSFETs is the result of further design improvements on ST's well-established stripbased PowerMESH™ layout. In addition to significantly lower on-resistance, the device offers superior dv/dt capability to ensure optimal performance even in the most demanding applications. The SuperMESH™ devices further complement an already broad range of innovative high voltage MOSFETs, which includes the revolutionary MDmesh™ products. Table 1. Device summary
