BSP50,115 Description

Short technical summary and product information.

The BSP50,115 is an NPN Darlington transistor designed for high-current gain applications. It features a collector-emitter voltage rating of 45 V and a continuous collector current capacity of 1 A. With a minimum DC current gain (hFE) of 2000 at Ic=500mA and Vce=10V, it provides efficient amplification and switching. The maximum collector-emitter saturation voltage is 1.3 V at Ib=500µA and Ic=500mA. Transition frequency is 200 MHz, making it suitable for moderate-speed switching. Power dissipation is rated at 1.25 W, with a maximum junction temperature of 150°C. The device is offered in a surface-mount SOT-223 package (TO-261-4 equivalent), enabling compact PCB designs. Typical applications include relay drivers, solenoid drivers, and low-side switching where high gain is required.
