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). Note 1: Pulse width 100 s, repetitive frequency = 100 Hz

Precautions
Please be careful of the followings. 1. 2. 3. 4. Soldering must be performed under the stopper. Soldering temperature : 260C max Soldering time : 5 s max When forming the leads, bend each lead under the 2 mm from the body of the device. Soldering must be performed after the leads have been formed. Radiant intensity falls over time due to the current which flows in the infrared LED. When designing a circuit, take into account this change in radiant power over time. The ratio of fluctuation in radiation intensity to fluctuation in optical output is 1 : 1.
