Absolute Maximum Ratings (Ta = 25°C)
Characteristics Symbol Rating Unit
Collector-base voltage VCBO 20 V
Collector-emitter voltage VCEO 12 V
Emitter-base voltage VEBO 3 V

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).
