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)＝Vcc－0.8V

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.

Soldering Iron

Each terminal is to go to the tip of soldering iron temperature less than 350℃ for 3 seconds within once

in less than the soldering iron capacity 25W. Leave two seconds and more intervals, and do soldering

of each terminal. Be careful because the damage of the product is often started at the time of the hand

solder.

Repairing

Repair should not be done after the device have been soldered. When repairing is unavoidable, a

double-head soldering iron should be used (as below figure). It should be confirmed beforehand

whether the characteristics of the device will or will not be damaged by repairing.
