Note:
1. The output voltage (Vout) is the product of photocurrent (IPH) and loading resistor (R

2. A right loading resistor shall be chosen to meet the requirement of maximum ambient light and

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 frequency is based on JEDEC-020D.
(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.
