Vishay Intertechnology introduced new -30 V and -40 V Automotive Grade p-channel TrenchFET power MOSFETs in the PowerPAK SO-8L package with gullwing leads for increased board-level reliability. Providing more than a 50 % reduction in mounting area compared to devices in the DPAK, the AEC-Q101 qualified SQJ407EP and SQJ409EP save PCB space and lower costs while delivering lower on-resistance than any MOSFET with gullwing leads in the 5 mm by 6 mm footprint.
Due to their high power requirements, motor drives and main power supplies in 12 V automotive systems require MOSFETs with extremely low on-resistance for applications such as reverse polarity battery protection and high side switching. With on-resistance down to 4.4 mΩ and 7.0 mΩ at 10 V, respectively, the Vishay Siliconix -30 V SQJ407EP and -40 V SQJ409EP are designed to meet this need. In addition, as p-channel MOSFETs, these devices make ideal load switches that do not require a charge pump to provide the positive gate bias needed by their n-channel counterparts.
The MOSFETs offer high-temperature operation to +175 °C, while their gullwing leads provide mechanical stress relief during temperature cycling, board flexing, vibration, and drop incidents, and offer excellent board-level reliability compared to rigid QFN packages. The gullwing leads also facilitate more consistent and dependable results from automatic optical inspection (AOI) processes.
Lead (Pb)-free, halogen-free, and RoHS-compliant, the devices are 100 % Rg and UIS tested.
Samples and production quantities of the SQJ407EP and SQJ409EP are available now.
