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.) x RL Vout(saturation)=Vcc-0.4V Page 4 of 11

9 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 10ºC ~ 30ºC and 90% RH. 3. After opening the package, the devices must be stored at 10ºC ~ 30ºC and 60% RH, and used within 168 hours (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 40ºC +5/-0ºC and < 5% RH (reeled/tubed/loose units) or 96 hours at 60ºC ±5ºC and < 5% RH (reeled/tubed/loose units) or 24 hours at 125ºC ±5ºC, not suitable for reel or tubes. Recommend Solder Profile 1. Soldering Condition 1.1 (A) Maximum Body Case Temperature Profile for evaluation of Reflow Profile. Note: Reference: IPC/JEDEC J-STD020D Page 9 of 11

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. Page 10 of 11

11 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.
