Product Summary

The STW9NB90 is a PowerMESH MOSFET. The new patent pending strip layout coupled with the Company’s proprietary edge termination structure, gives the lowest RDS(on) per area, exceptional avalanche and dv/dt capabilities and unrivalled gate charge and switching characteristics. The applicaitons of the STW9NB90 include high current, high speed switching, switch mode power supplies(SMPS) and DC-AC converters for welding equipmentand uninterruptible powersupplies and motor drive.
