650V automotive MOSFETs in TO-247

STMicroelectronics has launched industry's first 650V AEC-Q101 automotive qualified MOSFETs in the popular TO-247 package.

STW78N65M5 and STW62N65M5 with 650V rating provides greater safety margin when exposed to high-voltage spikes, enhancing the reliability of automotive power and control modules, as per ST. Both the devices feature low on-resistance of (RDS(ON)) of 0.032Ω and 0.049Ω respectively.

ST able to achieve this power density performance due to its MDmesh V super-junction technology, which produces high-voltage devices with very low RDS(ON) per die area allowing smaller package sizes. ST says Gate charge (Qg) and input capacitance are also low, resulting in outstanding Qg x RDS(ON) figure of merit (FOM) with high switching performance and efficiency. In addition, superior avalanche robustness ensures increased ruggedness at sustained high-voltage operation, claims ST.

ST’s 650V automotive-qualified MOSFETs in the TO-247package are in volume production, priced from $ 8.95 for the STW62N65M5 and $ 9.75 for the STW78N65M5, for orders over 1,000 pieces.
