BCX19 Description

Short technical summary and product information.

The BCX19 is an NPN bipolar junction transistor manufactured by On Semiconductor. It is designed for general-purpose switching and amplification applications in low-power circuits.

 

Key electrical specifications include a collector-emitter breakdown voltage (VCEO) of 45V, a collector current (IC) of 500mA, and a power dissipation of 300mW. The DC current gain (hFE) is a minimum of 100 at 100mA collector current and 1V collector-emitter voltage. The collector-emitter saturation voltage (VCE(sat)) is a maximum of 620mV at 50mA base current and 500mA collector current.

 

The device operates over a junction temperature range of -55°C to 150°C. It is housed in a compact SOT-23-3 surface-mount package, suitable for space-constrained PCB designs.

 

This transistor is suitable for low-power switching and signal amplification in consumer electronics, industrial control, and other general-purpose applications.
