• High DC current gain: hFE = 4000 (min) (VCE = 2 V, IC = 150 mA)
• Low saturation voltage: VCE (sat) = 1.5 V (max) (IC = 1 A, IB = 1 mA)

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).
