Key Features
- Darlington pair with built-in base resistor and flyback diode for simplified relay and motor drive circuits
- 45 V VCE and 500 mA IC ratings cover a wide range of low-power load switching applications
- SOT-223 package (SC-73, 4-pin) with collector tab for improved thermal dissipation in SMT designs
Applications
The BSP50,115 Darlington transistor is well suited for relay driving, solenoid control, and lamp switching in industrial automation and consumer appliance designs. Its minimum hFE of 2000 enables logic-level microcontroller outputs to directly drive loads up to 500 mA without additional drive circuitry. The integrated flyback diode makes it ideal for inductive load switching in motor control and power management systems.

Frequently Asked Questions
What are the key electrical ratings of the Nexperia BSP50,115 Darlington transistor?
The BSP50,115 is rated for a 45 V collector-emitter voltage (VCE), 500 mA maximum collector current (IC), and a minimum DC current gain (hFE) of 2000, enabling microcontroller logic levels to directly switch relay coils and other inductive loads.
How does the built-in flyback diode in the BSP50,115 simplify relay drive circuit design?
The integrated flyback diode in the BSP50,115 clamps inductive voltage spikes from relay coils and solenoids to safe levels without requiring an external diode, reducing component count and PCB area while protecting the transistor from transient voltages above 45 V.
Why is the SOT-223 package advantageous for the BSP50,115 in high-dissipation load switching?
The SOT-223 (SC-73, 4-pin) package of the BSP50,115 has a large collector tab that acts as a heatspreader, enabling better thermal management when switching loads near the 500 mA limit compared to smaller SOT-23 packages of equivalent Darlington transistors.
