Low Noise Audio Amplifier Applications
Low noise: NF = 3dB (typ.) RG = 100 , VCE = 6 V, IC = 100 μA,
f = 1 kHz
: NF = 0.5dB (typ.) RG = 1 k, VCE = 6 V, IC = 100 μA,
f = 1 kHz
High DC current gain: hFE = 200~700
High breakdown voltage: VCEO = 120 V
Low pulse noise. Low 1/f noise

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).
