Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

Handling and Mounting Precautions
* * * * * * Care must be taken in relation to the environment in which the device is to be installed. Oil or chemicals may cause the package to melt or crack. The device should be mounted on an unwarped surface. Do not apply stress to the resin at high temperature. The resin part is easily scratched, so avoid friction with hard materials. When installing the assembly board in equipment, ensure that this product does not come into contact with other components. Conversion efficiency falls over time due to the current which flows in the infrared LED. When designing a circuit, take into account this change in conversion efficiency over time. The ratio of fluctuation in conversion efficiency to fluctuation in infrared LED optical output is 1:1. IC/IF (t) Po (t) = IC/IF (0) Po (0)
Moisture-Proof Packing
* To avoid moisture absorption, the reel is packed in an aluminum bag that contains a desiccant with a humidity indicator. Since the optical characteristics of the photointerrputer may be affected during soldering by vaporization of the moisture which is absorbed in storable period, it should be stored under the following conditions: 1. If the aluminum bag has been stored unopened Temperature: 5 to 30C Relative humidity: 90% RH (max) Time: 12 months 2. If the aluminum bag has been opened Temperature: 5 to 30C Relative humidity: 70% RH (max) Time: 168 h 3. Baking should be conducted within 72 h after the humidity indicator shows > 30% or the bag seal date is over 12 months. The number of baking should be once. If the baking is conducted repeatedly, it may affect the peel-back force and cause a problem for mounting. Baking condition: 60 5C, 12 to 24 h Storage period: 12 months from the seal date on the label 4. When the photointerrupter is baked, protect it from electrostatic discharge. 5. Do not toss or drop to avoid damaging the moisture-proof bag.

(*)The product is evaluated using above reflow soldering conditions. No additional test is performed exceed the condition (i.e. the condition more than MAX values) as an evaluation. Please perform reflow soldering under the above conditions. * * * * The first reflow process should be performed under the above temperature profile within 168 h after opening the bag. If a second reflow process needs to be performed, it should be performed within 168 h of the first reflow under the above temperature profile. Storage conditions before the second reflow process: 30C, 70% RH (max) Do not perform wave soldering and manual soldering with a soldering iron.

Cleaning
When cleaning is required after soldering, Toshiba recommends the following cleaning solvents. It is confirmed that these solvents have no effect on semiconductor devices in our dipping test (under the recommended conditions). In selecting the one for your actual usage, please perform sufficient review on washing condition, using condition and etc. ASAHI CLEAN AK-225AES KAO CLEAN TROUGH 750H PINE ALPHA ST-100S TOSHIBA TECHNOCARE (FRW-17, FRW-1, FRV-100) : (made by ASAHI GLASS) : (made by KAO) : (made by ARAKAWA CHEMICAL) : (made by GE TOSHIBA SILICONES)
