• High speed switching: tr = 0.5 μs (max), tf = 0.3 μs (max) (IC = 0.8 A)
• High collector breakdown voltage: VCEO = 400 V
• High DC current gain: hFE = 40 (min) (IC = 0.2 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).
