The KSC1845FTA is an NPN epitaxial silicon transistor manufactured by ON Semiconductor. It is designed for audio frequency low-noise amplifier applications and is a complement to the KSA992. This device offers a maximum collector-emitter voltage of 120V and a maximum collector current of 50mA.
Key electrical characteristics include a minimum DC current gain (hFE) of 300 at 1mA and 6V, a maximum collector-emitter saturation voltage of 300mV at 1mA/10mA, and a transition frequency (fT) of 110MHz. The noise figure is a typical 7dB at 1kHz.
The transistor is housed in a TO-92-3 package with formed leads, designed for through-hole mounting on PCBs. It operates at a maximum junction temperature of 150°C and has a maximum power dissipation of 500mW. The device is Pb-Free.
Applications include audio preamplifiers, low-noise amplifiers, and consumer electronic circuits requiring low-level signal amplification.
