Current Transfer Ratio

Absolute Maximum Ratings (Ta = 25°C)

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) Derate 0.8mA above 70°C. (Note 2) 50% duty cycle, 1ms pulse width. Derate 1.6mA / °C above 70°C. (Note 3) Pulse width 1μs, 300pps. (Note 4) Derate 0.9mW / °C above 70°C. (Note 5) Derate 2mW / °C above 70°C.
