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: The junction-to-ambient thermal resistance, Rth(j-a), should be kept below 150î/W so that this product is not

exposed to a condition beyond the absolute maximum ratings.

Rth(j-a): Thermal resistance from the LED junction to ambient temperature

Note 1: Pulse width 10 ms, duty = 1/10
