• Complementary to 2SC5200
• Recommended for 100-W high-fidelity audio frequency amplifier
output stage.
Absolute Maximum Ratings (Ta = 25°C)
Characteristics Symbol Rating Unit
Collector-base voltage VCBO −230 V
Collector-emitter voltage VCEO −230 V
Emitter-base voltage VEBO −5 V
Collector current IC −15 A

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).
