MSOP-8EP 39 90°C/W (Note 5) 1.1W

U-DFN3030-6 14 69°C/W (Note 6) 1.47W

Notes: 5. 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.

6. 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

7. Dominant conduction path via exposed pad.

Operating Ambient Temperature Range

-40 +125 °C

Notes: 8. For improved accuracy LED current should be greater than 60mA.

9. Maximum LED current is also limited by ambient temperature and power dissipation such that junction temperature should be kept less than or equal

to +125°C.
