N-channel 500 V, 0.135 Ω, 21 A D²PAK, TO-220, TO-220FP, TO-247
MDmesh™ II Power MOSFET
Features
■100% avalanche tested
■Low input capacitance and gate charge
■Low gate input resistance
Applications
■Switching applications
Description
These devices are N-channel Power MOSFETs
developed using the second generation of
MDmesh™ technology. This revolutionary Power
MOSFET associates a vertical structure to the
company’s strip layout to yield one of the world’s
lowest on-resistance and gate charge. It is
therefore suitable for the most demanding high
efficiency converters.
