2SC1815 datasheet

Features :

1. High voltage and high current  VCEO=50V(Min), IC=150mA(Max)

2. Excellent hFE linearity : hFE(2)=100 (Typ) at VCE=6V,IC=150mA
hFE(IC=0.1mA) / hFE(IC=2mA=0.95(Typ))

3. Low noise.

4. Complementary to 2SA1015.


Advantages  Vs Disadvantages


1. High current gain, which allows for amplification of small signals
2. Low noise, which makes it suitable for use in audio circuits
3. Low voltage drop, which results in less power dissipation and higher efficiency
4. High frequency response, which makes it suitable for use in high-frequency circuits
5. Small size, which allows for compact circuit designs


1. Low maximum collector current, which restricts its use in high-power applications
2. Low maximum collector-emitter voltage, which restricts its use in high-voltage applications
3. Limited temperature range, which can be a concern in some applications


Maximum Ratings

1. Collector-Base Voltage : VCBO = 60 V
2. Collector-Emitter Voltage : VCEO = 50 V
3. Emitter-Base Voltage : VEBO = 5 V
4. Collector Current -Continuous : IC = 150 mA
5. Base Current : IB = 50 mA
6. Collector Dissipation : PC = 400 mW


1. Audio frequency general purpose amplifier applications
