According to the company, the 650V rating provides greater safety margin when exposed to high voltage spikes, enhancing the reliability of automotive power and control modules.
The devices also offer a low on-resistance (RDS(ON)) of 0.032? and 0.049? respectively, thanks to ST's proprietary MDmesh V super-junction technology.
Gate charge and input capacitance are also low, resulting in a superior Qg x RDS(ON) figure of merit with high switching performance and efficiency.
