The BST50,115 is an NPN Darlington transistor manufactured by Nexperia USA Inc. It combines two bipolar transistors in a Darlington configuration to achieve a high DC current gain of at least 2000 at 500mA collector current and 10V collector-emitter voltage. The device is rated for a maximum collector-emitter breakdown voltage of 45V and a maximum collector current of 1A, with a maximum power dissipation of 1.3W.
The transistor offers a transition frequency of 200MHz and a maximum collector-emitter saturation voltage of 1.3V at 500µA base current and 500mA collector current. It is designed for surface-mount assembly in the TO-243AA package, also known as the SOT-89 supplier device package, which provides a compact footprint suitable for space-constrained PCB designs.
With its high current gain, the BST50,115 is well-suited for applications requiring high sensitivity or low base-drive requirements, such as relay drivers, solenoid drivers, and other switching circuits where a small input current must control a larger load current. The device operates with a maximum junction temperature of 150°C, supporting use in a range of ambient temperature environments.
The SOT-89 package includes a tab for improved thermal performance, aiding heat dissipation in power-switching applications. The surface-mount format is compatible with standard reflow soldering processes, facilitating automated assembly in high-volume manufacturing.
