BSP50

Single Bipolar Transistors Overview

The BSP50 is an NPN Darlington transistor manufactured by onsemi, housed in a surface-mount SOT-223 package. It features a collector-emitter voltage of 45 V and a maximum DC collector current of 0.8 A. The device has a power dissipation rating of 1.5 W and operates within a temperature range of -55°C to +150°C.

Single Bipolar Transistors Feature Summary

• High current capability with a maximum collector current of 1 A
• Low voltage operation suitable for various switching applications

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Driver stages for relays or lamps
• Audio amplifier output stages

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin carefully, as BSP50 was originally a Philips/NXP part number. Current listings may indicate onsemi as the supplier. Confirm RoHS compliance status and exact package dimensions against the specific datasheet revision before integration into designs requiring strict environmental standards.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring high gain and moderate current handling in a compact surface-mount form factor. Ensure thermal management strategies account for the 1.5 W power dissipation limit in the SOT-223 package. Compare against alternative Darlington transistors if higher voltage ratings or different pin configurations are required.

Single Bipolar Transistors Part Context

The BSP50 belongs to the family of NPN Darlington transistors designed for general-purpose amplification and switching. Originally specified by Philips Semiconductors, these devices are characterized by high current gain and low saturation voltages, making them suitable for driving loads directly from logic outputs.
