I2PAK (TO-263) provides excellent thermal transfer to the PCB.","working_principle":"MDmesh K5 uses multiple vertical p-n columns in the drift region (superjunction) to reduce RDS(on) below the silicon limit while maintaining 800V breakdown. The charge-balanced structure achieves low Qg for fast switching. The strip layout provides uniform current density and high dv\/dt ruggedness.","pin_description":"
