Product Summary

The STW20NB50 is a N channel 500V 0.22W 20A to-247 power MESH MOSFET. Using the latest high voltage technology, STMicroelectronics of the STW20NB50 has designed an advanced family of power Mosfets with outstanding performances. The new patent pending strip layout of the STW20NB50 coupled with the Companys proprietary edge termination structure, gives the lowest RDS(on) per area, exceptional avalanche and dv/dt capabilities and unrivalled gate charge and switching characteristics.
