Asymmetric Package Optimizes Low-Side MOSFET RDS(on) and Saves Space in Synchronous DC/DC Converters
MALVERN, PA -- (Marketwired) -- 12/12/13 --
Vishay Intertechnology, Inc. (NYSE:VSH) today launched two new AEC-Q101-qualified, 40 V, dual n-channel TrenchFET® power MOSFETs in the asymmetric PowerPAK® SO-8L package. For automotive applications, the Vishay Siliconix SQJ940EP and SQJ942EP combine both high- and low-side MOSFETs required for high-efficiency synchronous DC/DC buck converters in one compact 5 mm by 6 mm package, saving space compared to using discrete MOSFETs while offering a low-side maximum on-resistance down to 6.4 milliohms.
Among the industry's first automotive-qualified dual MOSFETs in an asymmetric package, where the size of the low-side MOSFET is increased for lower conduction losses, the MOSFETs released today offer high-temperature operation to +175 °C to provide the ruggedness and reliability required for applications anywhere inside vehicles. The devices are particularly well suited to vehicle telematics, such as the radio and GPS systems.
The SQJ940EP and SQJ942EP offer designers a choice of different on-resistance values. At the 10 V rating, the SQJ940EP offers low maximum on-resistance of 6.4 milliohms for the Channel 2 low-side MOSFET and 16 milliohms for the Channel 1 high-side MOSFET. Compared with dual symmetrical solutions, the SQJ940EP offers 31 % lower low-side on-resistance while still maintaining a compact outline. The SQJ942EP offers maximum on-resistance of 11 milliohms at 10 V for the low-side MOSFET and 22 milliohms for the high-side MOSFET.
100 % Rg- and UIS-tested, the MOSFETs are RoHS-compliant and halogen-free.
Samples and production quantities of the SQJ940EP and SQJ942EP are available now, with lead times of 14 to 16 weeks for larger orders.
