Exposed thermal pad (reference only, terminal #1 identiﬁer appearance at supplier discretion)

Reference land pattern layout (reference IPC7351 QFN50P400X400X80-25W6M); 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)
