BCX19LT1 Description

Short technical summary and product information.

The BCX19LT1 is an NPN bipolar junction transistor manufactured by On Semiconductor. It is designed for general-purpose switching and amplification applications.

 

Electrical characteristics include a maximum collector-emitter voltage of 45V, collector-base voltage of 50V, and emitter-base voltage of 5V. The continuous collector current is 500mA. DC current gain (hFE) is minimum 100 at 100mA, 1V, and 70 at 300mA, 1V. Maximum collector-emitter saturation voltage is 620mV at 50mA base current and 500mA collector current.

 

The device is housed in a surface-mount SOT-23-3 (TO-236) package. It operates over a junction temperature range of -55°C to 150°C. Power dissipation is 225mW on FR-5 board and 300mW on alumina substrate. Thermal resistance junction-to-ambient is 556°C/W on FR-5 and 417°C/W on alumina.

 

This transistor is suitable for low-power switching and linear amplification in portable electronics, automotive, and industrial control systems. The SOT-23 package enables compact PCB designs.
