STMicroelectronics is expanding three of its advanced high-voltage power MOSFET families with the introduction of two new power packages, making energy-conscious equipment such as battery chargers, solar microinverters and computer power supplies even more compact, robust and reliable.
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 5mm x 6mm footprint of a standard 100V PowerFLAT 5x6. This is 52% smaller than the popular DPAK footprint. In addition, the package is only 1mm high and features a large exposed metal drain pad that maximizes heat dissipation into pc-board thermal vias. This combination of features simultaneously increases high-voltage capability, ruggedness, reliability, and system power density.
ST is introducing three 650V MDmesh™ V MOSFETs in the PowerFLAT 5x6 HV package, priced from $2.20 for the STL12N65M5, and four 800V SuperMESH 5 MOSFETs in the PowerFLAT 5x6 VHV package, which is optimized for very high voltage ratings, priced from $1.50 for the STL2N80K5. All prices are for orders over 1000 pieces. In addition, ST has started sampling two new 600 V fast-switching MDmesh II Plus low Qg MOSFETs in PowerFLAT 5x6 HV.
