Audio Frequency Amplifier Applications
Unit: mm
• Small package
• High voltage: V_CEO = −50 V (min)
• High h_FE: h_FE = 70~400
• Excellent h_FE linearity: h_FE (I_C = −0.1 mA)/h_FE (I_C = −2 mA) = 0.95 (typ.)
• Low noise: NF = 1dB (typ.), 10dB (max)
• Complementary to 2SC2458

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).
