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).

Measurements are made with RL = 10 kΩ between output and ground. Optical measurements are made using small-angle incident radiation from an LED optical source. The 640 nm input irradiance Ee is supplied by an AlInGaP LED with peak wavelength λp = 640 nm. 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.

To ensure the package molding compound contains the smallest amount of absorbed moisture possible, each device is dry−baked prior to being packed for shipping. Devices are packed in a sealed aluminized envelope with silica gel to protect them from ambient moisture during shipping, handling, and storage before use. This package has been assigned a moisture sensitivity level of MSL 3 and the devices should be stored under the following conditions: Temperature Range Relative Humidity Total Time Opened Time 5°C to 50°C 60% maximum 6 months from the date code on the aluminized envelope — if unopened 168 hours or fewer Rebaking will be required if the devices have been stored unopened for more than 6 months or if the aluminized envelope has been open for more than 168 hours. If rebaking is required, it should be done at 90°C for 4 hours.
