Description
This is N-CHANNEL 700V – 1Ω – 7.5A, MOSFET.
The SuperMESH series is obtained through an extreme optimization of ST’s well established stripbased PowerMESH layout. In addition to pushing on-resistance significantly down, special care is taken to ensure a very good dv/dt capability for the most demanding applications. Such series complements ST full range of high voltage MOSFETs including revolutionary MDmesh products.
