STN749

Single Bipolar Transistors Overview

The STN749 is a PNP bipolar junction transistor (BJT) manufactured by STMicroelectronics. It is housed in an SOT-223-4 surface-mount package and utilizes silicon technology. The device supports a maximum DC collector current of 3 A with a power dissipation rating of 1.6 W. Voltage specifications include a collector-emitter voltage (VCEO) of 25 V, a collector-base voltage (VCBO) of 35 V, and an emitter-base voltage (VEBO) of 5 V. It operates within a temperature range of -65°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify component authenticity through authorized channels as the part status is discontinued. Confirm RoHS compliance details directly with the manufacturer or supplier documentation. Ensure the SOT-223-4 package matches your PCB footprint requirements. Check for regional sales restrictions that may affect availability. Validate that the specific lot meets your thermal management needs given the 1.6 W dissipation limit.

Single Bipolar Transistors Selection Notes

Select this component when a single PNP BJT capable of handling up to 3 A is required in a compact SMD form factor. Consider the 25 V VCEO rating against your circuit's maximum voltage swings. Evaluate the thermal performance capabilities relative to your expected power dissipation levels. Ensure compatibility with surface-mount assembly processes suitable for the SOT-223-4 package type.
