C1815 is an NPN transistor, which operates when a positive voltage is applied. Applying a positive voltage between the base and emitter turns the transistor on, allowing current to flow between the collector and emitter. This allows you to amplify small input signals or control switches.

Description
C1815 is an electronic component commonly used as an NPN transistor. These transistors are used in a variety of applications, including amplification of small signals, switching, and current control.
Features
• High voltage and high current: VCEO= 50 V (min), IC= 150 mA (max)
• Excellent hFElinearity :
(1) hFE (2)= 100 (typ.) at VCE= 6 V, IC= 150 mA
(2) hFE(IC= 0.1 mA)/hFE(IC= 2 mA) = 0.95 (typ.)
• Low noise: NF = 1dB (typ.) at f = 1 kHz
• Complementary to 2SA1015 (O, Y, GR class)
Pinout

The pin configuration of this transistor consists of a base, collector, and emitter.
Absolute Maximum Ratings (Ta = 25°C)
1. Collector to Base Voltage : Vcbo = 60 V
2. Collector to Emitter Voltage : Vceo = 50 V
3. Emitter to Base Voltage : Vebo = 5 V
4. Collector Current : Ic = 150 mA
5. Total Dissipation : Pc = 400 mW
6. Junction Temperature : Tj = 125°C
7. Storage Temperatue : Tsg = -55 ~ +150°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.
Applications
1. Audio Frequency
2. General Purpose Amplifier
