Given an existing thermal resistance of 8°C/W between the junction and the solder point, it is crucial for the end product to be designed in a manner that minimizes the thermal resistance from the solder point to ambient in order to optimize lamp life and optical characteristics. 0 100 200 300 400 500 600 700 800 900 1000 0.0 1.0 2.0 3.0 4.0 5.0 Forward Voltage (V) Cool White Neutral White, Warm White, Blue and Royal Blue Rth,j-a 10 Rth,j-a 12 Max Current mA 1000 Ta Max Derated Ta Max Derated Tj max °C 150 °C mA mA °C mA mA Max Vf V 4.3 0 3488.4 1000.0 0 2907.0 1000.0 Max amb °C 150 107 1000.0 1000.0 98.4 1000.0 1000.0 150 0.0 0.0 150 0.0 0.0 0 200 400 600 800 1000 1200 0 25 50 75 100 125 150 Ambient Temperature (°C) Rj-a = 10°C/W Rj-a = 12°C/W Rj-a = 15°C/W Rj-a = 20°C/W 0 100 200 300 400 500 600 700 800 0 25 50 75 100 125 150 Ambient Temperature (°C) Rj-a = 10°C/W Rj-a = 12°C/W Rj-a = 15°C/W Rj-a = 20°C/W Rth,j-a 10 Rth,j-a 12 Max Current mA 1000 Ta Max Derated Ta Max Derated Tj max °C 150 °C mA mA °C mA mA Max Vf V 4.3 0 3488.4 1000.0 0 2907.0 1000.0 Max amb °C 150 107 1000.0 1000.0 98.4 1000.0 1000.0 150 0.0 0.0 150 0.0 0.0 0 200 400 600 800 1000 1200 0 25 50 75 100 125 150 Ambient Temperature (°C) Rj-a = 10°C/W Rj-a = 12°C/W Rj-a = 15°C/W Rj-a = 20°C/W 0 100 200 300 400 500 600 700 800 0 25 50 75 100 125 150 Ambient Temperature (°C) Rj-a = 10°C/W Rj-a = 12°C/W Rj-a = 15°C/W Rj-a = 20°C/W |
