1. Mounted on a multi-layer FR4 PCB with a dissipating copper surface on the top side of 6 cm2 (with a

thickness of 35 µm).

2. Mounted on a multi-layer FR4 PCB with a dissipating copper surface on the top side of 6 cm2 (with a

thickness of 35 µm), 16 via holes and a ground layer.

3. Mounted on a multi-layer FR4 PCB without any heat-sinking surface on the board.

4. Mounted on a double-layer FR4 PCB with a dissipating copper surface of 0.5 cm2 on the top side plus 6

cm2 ground layer connected through 18 via holes (9 below the IC).
