Internal schematic diagram Zener-protected D(2, TAB) Applications Switching applications Description G(1) These devices are N-channel Power MOSFETs developed using SuperMESH 5 technology. This revolutionary, avalanche-rugged, high voltage Power MOSFET technology is based on an innovative proprietary vertical structure. The S(3) result is a drastic reduction in on-resistance and AM01476v1 ultra low gate charge for applications which require superior power density and high efficiency. Table 1.
