Description
G(1)
This very high voltage N-channel Power MOSFET is designed using MDmesh™ K5
technology based on an innovative proprietary vertical structure. The result is a
dramatic reduction in on-resistance and ultra-low gate charge for applications
requiring superior power density and high efficiency.

The built-in back-to-back Zener diodes are specifically designed to enhance the ESD performance of the device.
The Zener voltage facilitates efficient and cost-effective device integrity protection, thus eliminating the need for
additional external componentry.
