ST’s advanced PowerFLAT 5x6 HV and PowerFLAT 5x6 VHV packages provide the large insulation path lengths and clearances required for operation at up to 650V or 800V, within the same 5 x 6 mm footprint of a standard 100V PowerFLAT 5x6. This is 52% smaller than the DPAK footprint. In addition, the package is only 1mm high and features a large exposed metal drain pad that maximises heat dissipation into pc-board thermal vias. This increases high-voltage capability, ruggedness, reliability, and system power density.
Three 650V MDmesh V MOSFETs in the PowerFLAT 5x6 HV package are priced from $2.20 (1000) for the STL12N65M5, and four 800V SuperMESH 5 MOSFETs in the PowerFLAT 5x6 VHV package, which is optimised for very high voltage ratings are priced from $1.50 for the STL2N80K5. Also sampling are two 600 V fast-switching MDmesh II Plus low Qg MOSFETs in PowerFLAT 5x6 HV.
