AEC-Q101-Qualified FETs Packaged for Synchronous Bucks

To save space and power in high-efficiency synchronous buck converters for automotive applications, Vishay Intertechnology, Inc. today introduced the industry's first AEC-Q101-qualified 12V and 20V MOSFETs in a dual asymmetric power package. The Vishay Siliconix SQJ202EP and SQJ200EP n-channel TrenchFET® devices each combine a high- and low-side MOSFET in the compact 5mm by 6mm PowerPAK® SO-8L dual asymmetric package, with low-side maximum on-resistance down to 3.3mΩ.

By co-packaging two MOSFETs in an asymmetric package — with a larger low-side MOSFET for lower on-resistance and smaller high-side MOSFET for faster switching — the 12V SQJ202EP and 20V SQJ200EP provide high-performance alternatives to standard dual devices, which restrict the optimum combination of MOSFETs for high-current, high-frequency synchronous buck designs. Compared to using discrete components, the devices occupy less board space and can facilitate more compact PCB layouts.

The devices released today offer high-temperature operation to +175 degrees C to provide the ruggedness and reliability required for automotive applications such as infotainment, telematics, navigation, and LED lighting. The SQJ202EP is well-suited for applications with bus voltages ≤8V and offers extremely low maximum on-resistance down to 3.3mΩ for the Channel 2 low-side MOSFET.

For applications with higher bus voltages, the 20V SQJ200EP features a slightly higher maximum on-resistance of 3.7mΩ. Both parts are 100% tested for gate resistance and avalanche, and they are RoHS-compliant and halogen-free.

Samples and production quantities of the SQJ200EP and SQJ202EP are available now, with lead times of 12 weeks for large orders. Pricing for U.S. delivery starts at $0.29 per piece in 100,000-piece quantities.
