Test method
The specified electro-optical characteristics are valid under the following conditions.
1. Measurement environment
A place without extreme light reflections.
2. External light
The environment contains an ordinary, white fluorescent lamp without high frequency modulation. The color
temperature is 2856K and the illumination at the IR receiver is less than 10 Lux (Ev≦10Lux).
3. Standard transmitter
The test transmitter is calibrated by using the circuit shown in figure 2. The radiation intensity of the transmitter is
adjusted until Vo=400mVp-p. Both, the test transmitter and the photo diode, have a peak wavelength of 940nm.
The photo diode for calibration is PD438B (λp=940nm, Vr=5V).

Recommended method of storage
The following are general recommendations for moisture sensitive level (MSL) 4 storage and use:
1. Shelf life in sealed bag from the bag seal date: 12 months at < 40 °C and < 90% relative humidity (RH)
2. After bag is opened, devices that will be subjected to reflow solder or other high temperature process must mounted
within 72 hours of factory conditions < 30 °C/60%RH.
3. If the moisture absorbent material (silica gel) has faded away or the IRM has exceeded the storage time. Baking
treatment is required, refer to IPC/JEDEC J-STD-033 for bake procedure or recommend the conditions: 60±5C for 96
hours.
ESD Precaution
Proper storage and handing procedures should be followed to prevent ESD damage to the devices especially when they
are removed from the Anti-static bag. Electro-Static Sensitive Devices warning labels are on the packing.
