FJX4003RTF Description

Short technical summary and product information.

This is a PNP pre-biased bipolar junction transistor from On Semiconductor, designed for surface mount applications. It integrates bias resistors, simplifying circuit design by reducing external component count.

 

Key electrical specifications include a collector-emitter breakdown voltage of 50V, a maximum collector current of 100mA, and a power dissipation of 200mW. The DC current gain (hFE) is minimum 56 at 5mA, 5V, and the transition frequency is 200MHz. The collector-emitter saturation voltage is 300mV maximum at 500µA base current and 10mA collector current.

 

The transistor includes a built-in base resistor of 22 kΩ, making it suitable for switching and amplification circuits where space and component count are critical. It is housed in a compact SOT-323 (SC-70) surface mount package, ideal for high-density PCB designs.

 

The device is RoHS3 compliant and has an MSL of 1 (unlimited), ensuring reliability in various manufacturing environments. It is commonly used in portable electronics, load switches, and signal processing circuits.
