The photodiode active area is 0.5 mm × 0.5 mm and the sensors respond to light in the range of 320 nm to 1050 nm. Output voltage is linear with light intensity (irradiance) incident on the sensor over a wide dynamic range. These devices are supplied in a low-profile surface-mount package (T).

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltages are with respect to GND. 2. Output may be shorted to supply.

Measurements are made with RL = 10 kΩ between output and ground. 4. Optical measurements are made using small-angle incident radiation from an LED optical source. 5. The 640 nm input irradiance Ee is supplied by an AlInGaP LED with peak wavelength λp = 640 nm. 6. Irradiance responsivity is characterized over the range VO = 0.2 to 4 V. The best-fit straight line of Output Voltage VO versus irradiance Ee over this range may have a positive or negative extrapolated VO value for Ee = 0. For low irradiance values, the output voltage VO versus irradiance Ee characteristic is non linear with a deviation toward VO = 0, Ee = 0 origin from the best-fit straight line referenced above.
