OptiMOS™ 5 low-voltage power MOSFET 150 V in PQFN 3.3x3.3 Source-Down DSC package The IQE220N15NM5SC is part of the Source-Down family with an RDS(on) of 22 mOhm. The Source-Down technology introduces a flipped silicon die, offering increased thermal capability, improved power density and layout possibilities. The dual-side cooling package dissipates three times more power than to the overmolded package. The new technology can be found in two different footprints Standard-Gate and Center-Gate (optimized for parallelization).
