The onsemi PN4121 is a PNP bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. This through-hole component, housed in a TO-92-3 package, features a collector-emitter breakdown voltage of 40V and a maximum continuous collector current of 100mA. With a maximum power dissipation of 625mW at 25°C ambient temperature, it offers a minimum DC current gain (hFE) of 60 at 1mA collector current and 1V collector-emitter voltage. The saturation voltage (Vce(sat)) is specified as 300mV maximum at 5mA base current and 50mA collector current. The PN4121 exhibits a low collector cutoff current of 25nA. This component finds utility in consumer electronics, industrial control systems, and telecommunications equipment.
