2SC1959 transistor



The 2SC1959 is a silicon NPN bipolar junction transistor (BJT) primarily designed for general-purpose amplifier applications.

1. Voltage Ratings:

(1) Collector-Base Voltage (VCBO): Typically around 35V (Volts). This is the maximum voltage that can be applied between the collector and base terminals when the emitter is open.

(2) Collector-Emitter Voltage (VCEO): Typically around 30V (Volts). This is the maximum voltage that can be applied between the collector and emitter terminals when the base is open.
Current Ratings:

2. Continuous Collector Current (IC):

Typically around 500mA (Milliamperes). This is the maximum continuous current that the transistor can handle flowing from the collector to the emitter.


1. Excellent hFE linearity : hFE (2) = 25 (min): VCE = 6 V, IC = 400 mA

2. 1 watt amplifier applications.

3. High Transition Frequency

4. Complementary to 2SA562TM.
