TOSHIBA Transistor Silicon NPN Epitaxial Type (PCT Process)
2SC4944
2SC4944
Audio Frequency General Purpose Amplefier Applications
Unit: mm
• Small package (dual type)
• High voltage and high current: VCEO = 50 V, IC = 150 mA (max)
• High hFE: hFE = 120 to 400
• Excellent hFE linearity: hFE (IC = 0.1 mA)/hFE (IC = 2 mA) = 0.95 (typ.)
• Complementary to 2SA1873

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).
