Heatsink Mounting Guidelines

The R48.B package option has a heatsink mounted on the

underside of the package. The following JESD51-5 guidelines

may be used to mount the package:

1. Place a thermal land on the PCB under the heatsink.

2. The land should be approximately the same size as to 1mm

larger than the 9x9mm heat sink.

3. Place an array of thermal vias below the thermal land.

- Via array size: ~8 x 8 = 64 thermal vias

- Via diameter: ~0.3mm drill diameter with plated copper on

the inside of each via.

- Via pitch: ~1.2mm.

- Vias should drop to and contact as much buried metal area

as feasible to provide the best thermal relief.

Heatsink Electrical Potential

The heatsink is electrically isolated and unbiased. The heatsink

may be electrically connected to any potential, which offers the

best thermal relief through conductive mounting materials

(conductive epoxy, solder, etc.) or may be left unbiased through

the use of electrically non-conductive mounting materials

(non-conductive epoxy, Sil-pad, kapton film, etc.).
