Due to their high power requirements, motor drives and main power supplies in 12V 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 4.4mΩ and 7.0mΩ at 10V, respectively, the Vishay Siliconix -30V SQJ407EP and -40V 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 released today 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.
