Notes:

5. Dominant conduction path via exposed pad.

6. Test condition for MSOP-8EP: Device mounted on FR-4 PCB (51mm x 51mm 2oz copper, minimum recommended pad layout on top layer and

thermal vias to bottom layer ground plane. For better thermal performance, larger copper pad for heat-sink is needed.

7. Test condition for U-DFN3030-6: Device mounted on FR-4 PCB (51mm x 51mm 2oz copper, minimum recommended pad layout on top layer and

thermal vias to bottom layer with maximum area ground plane. For better thermal performance, larger copper pad for heat-sink is needed

Notes:

8. Maximum LED current is also limited by ambient temperature and power dissipation such that junction temperature should

be kept less than or equal +125°C.

9. For VCC < 3.5V, Maximum LED current is 50mA.
