BCX70G Description

Short technical summary and product information.

The BCX70G is an NPN bipolar junction transistor manufactured by ON Semiconductor (formerly Fairchild Semiconductor). It is designed for general-purpose amplification and switching applications in low-power circuits.

 

Key electrical specifications include a maximum collector-emitter breakdown voltage of 45V, a maximum collector current of 200mA, and a maximum power dissipation of 350mW. The device offers a minimum DC current gain (hFE) of 120 at a test condition of Ic=2mA and Vce=5V, and a typical transition frequency of 125MHz. The maximum collector-emitter saturation voltage is 550mV at Ib=1.25mA and Ic=50mA.

 

The transistor is housed in a TO-236-3 / SC-59 / SOT-23-3 surface-mount package, making it suitable for compact PCB designs. It is recommended for use in low-power signal amplification, driver stages, and general-purpose switching circuits where high gain and moderate frequency performance are required.
