This revolutionary, avalanche-rugged, high voltage Power MOSFET technology is based on an innovative proprietary vertical structure. The result is a drastic reduction in on-resistance and ultra low gate charge for applications which require superior power density and high efficiency. Table 1.

Symbol BVGSO Gate-source Zener diode Parameter Test conditions Gate-source breakdown voltage Igs 1mA, (open drain) The built-in-back Zener diodes have specifically been designed to enhance not only the device's ESD capability, but also to make them safely absorb possible voltage transients that may occasionally be applied from gate to source. In this respect the Zener voltage is appropriate to achieve an efficient and cost-effective intervention to protect the device's integrity. These integrated Zener diodes thus avoid the usage of external components. Doc ID 16744 Rev 5 5/21 Electrical characteristics STx21N90K5 2.1 Electrical characteristics (curves) Figure 2.
