Converting Photocurrent to Voltage

Amp
Iph
Vout

CL
RL
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
1. Do not open moisture proof bag before devices are ready to use.
2. Shelf life in sealed bag from the bag seal date:
18 months at 10°C~30°C and < 90% RH.
3. After opening the package, the devices must be stored at 10°C~30°C and 60%RH, and used within 1 year
(floor life).
4. If the moisture absorbent material (desiccant material) has faded or unopened bag has exceeded the shelf
life or devices (out of bag) have exceeded the floor life, baking treatment is required.
5. If baking is required, refer to IPC/JEDEC J-STD-033 for bake procedure or recommend the following
conditions:
192 hours at 40°C +5/–0°C and < 5 % RH (reeled/tubed/loose units) or
96 hours at 60°C ± 5°C and < 5 % RH (reeled/tubed/loose units) or
24 hours at 125°C ± 5°C, not suitable for reel or tubes.
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.
