2SC2240

Low Noise Audio Amplifier Applications

The 2SC2240 is a transistor for low frequency and low noise

applications. This device is designed to lower noise figure in the region of

low signal source impedance, and to lower the pulse noise. This is

recommended for the first stages of Equalizer amplifiers.

• Low noise: NF = 4dB (typ.) RG = 100 Ω, VCE = 6 V, IC = 100 μA,

f = 1 kHz

: NF = 0.5dB (typ.) RG = 1 kΩ, VCE = 6 V, IC = 100 μA,

f = 1 kHz

• Low pulse noise: Low 1/f noise

• High DC current gain: hFE = 200~700

• High breakdown voltage: VCEO = 120 V

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).
