FJN4303RTA Description

Short technical summary and product information.

The FJN4303RTA is a PNP pre-biased bipolar junction transistor manufactured by ON Semiconductor. This device integrates a 22kΩ base resistor internally, simplifying circuit designs by reducing external component count. It supports a collector-emitter voltage of 50V and a collector current of 100mA, with a maximum power dissipation of 300mW.

 

The transistor offers a minimum DC current gain (hFE) of 56 at 5mA/5V, a saturation voltage of 300mV maximum at 500µA/10mA, and a transition frequency of 200MHz. With a TO-92-3 through-hole package, the FJN4303RTA is suitable for low-power switching and signal amplification applications.

 

The component is RoHS3 compliant according to existing database records, though this has not been independently verified. It is commonly used in low-frequency amplifier stages, interface circuits, and general-purpose switching.
