Note:
1. The output voltage (Vout) is the product of photocurrent (IPH) and loading resistor (RL)
2. A right loading resistor shall be chosen to meet the requirement of maximum ambient light,
and output saturation voltage:
Vout(max.) = Iout(max.) × RL Vout(saturation)Vcc0.8V
3. To avoid 60Hz ripple from fluorescent lamps, we suggest that the time constant must be
greater than 0.5 second:
RL × CL 0.5 (empirical data)

Recommended method of storage
Reflow Terms: JEDEC Level 2 Specification
Dry box storage is recommended as soon as the aluminum bag has been opened prevent
moisture absorption. The following conditions should be observed, if dry boxes are not available:
z Storage temperature 10 to 30
z Storage humidity 60%RH max
After more than one year under these conditions moisture content will be too high for Reflow soldering.
In case of moisture absorption, the devices will recover to former condition by drying under the following
condition:
192 hours at 40+5/-0 and 5%RH (dry air / nitrogen), or
96 hours at 60+5 and < 5%RH for all device containers, or
24 hours at 125+5 not suitable for reel or tubes
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.
Recommended Solder Profile
Notice:
(1) Reflow soldering should not be done more than two times.
(2) When soldering, do not put stress on the devices during heating.
(3) After soldering, do not warp the circuit board.
