TOSHIBA Transistor Silicon PNP Epitaxial Type (PCT process)
2SA1048(L)
Audio Frequency Amplifier Applications
Low Noise Audio Frequency Applications
• Small package.
• High voltage: VCEO = −50 V (min)
• High hFE: hFE = 70~400
• Excellent hFE linearity: hFE (IC = −0.1 mA)/hFE (IC = −2 mA) = 0.95 (typ.)
• Low noise: NF = 0.2dB (typ.), 3dB (max)
• Complementary to 2SC2458 (L).
Absolute Maximum Ratings (Ta = 25°C)
Characteristics Symbol Rating Unit
Collector-base voltage VCBO −50 V
Collector-emitter voltage VCEO −50 V
Emitter-base voltage VEBO −5 V
Collector current IC −150 mA
Base current IB −50 mA
Collector power dissipation PC 200 mW
Junction temperature Tj 125 °C
Storage temperature range Tstg −55~125 °C
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).
