Brand: Jj electronic
The JJ Electronic JJ243 is a high-power bipolar junction transistor (BJT) designed for audio and power amplifier applications. It is a dual-emitter (push-pull) device that can deliver a maximum power output of 36 watts at a collector-emitter voltage of 30 volts, making it an excellent choice for driving high-impedance loudspeakers. It features a low noise and low current gain, as well as a mid-gain beta of approximately 125, which allows it to boost the output of a preamp stage before power amplification. Additionally, it has a maximum collector current of 350 milliamperes (mA), a maximum collector-base voltage of 75 volts (VCEO), and a maximum collector-emitter voltage (VCEmax) of 60 volts at a maximum collector current of 5 mA. Overall, the JJ243 is a reliable and high-performance BJT that offers excellent audio fidelity and power handling capability.
