ST claims first with 650V automotive mosfets

The STW78N65M5 and STW62N65M5 from STMicroelectronics are claimed to be the industry's first 650V AEC-Q101 automotive qualified mosfets available in a TO-247 package.

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.
