C Reference land pattern layout (reference IPC7351
QFN50P600X600X100-37V1M); All pads a minimum of 0.20 mm from
all adjacent pads; adjust as necessary to meet application process
requirements and PCB layout tolerances; when mounting on a
multilayer PCB, thermal vias at the exposed thermal pad land can
improve thermal dissipation (reference EIA/JEDEC Standard JESD51-5)
D Coplanarity includes exposed thermal pad and terminals
