2SB1124T-TD-E

Single Bipolar Transistors Overview

The onsemi 2SB1124T-TD-E is a PNP bipolar junction transistor (BJT) designed for high-current switching applications. It features a maximum collector-emitter voltage of -50V and a continuous collector current capacity of -3A. The device utilizes FBET and MBIT processes to achieve low collector-to-emitter saturation voltage and fast switching speeds. Packaged in the PCP (SC-62/SOT-89/TO-243) surface-mount format, it offers large current capacity and wide safe operating area (ASO). Key electrical limits include a collector-base voltage of -60V, emitter-base voltage of -6V, and power dissipation up to 500mW at 25°C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TD-E' against the manufacturer's latest datasheet to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact pinout and thermal characteristics required for the target PCB layout. Cross-reference the component revision history to account for any manufacturing location changes or minor parameter updates documented in product change notifications.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -3A current capability and -50V breakdown is required in a surface-mount form factor. The low VCE(sat) makes it suitable for applications where minimizing conduction loss is critical. Compare the PCP package dimensions against available board space. Consider the thermal resistance and power derating curves if operating above 25°C ambient temperature to ensure reliability within the specified junction temperature limits.

Single Bipolar Transistors Part Context

This component belongs to the 2SB1124 series of single PNP bipolar transistors manufactured by onsemi. It is part of a family that includes complementary NPN devices like the 2SD1624, designed for matched performance in switching circuits. The series leverages advanced epitaxial planar silicon technology to deliver robust performance in high-current applications while maintaining a compact footprint suitable for modern electronic assemblies.

Single Bipolar Transistors Replacement Considerations

Check for direct equivalents such as the 2SB1124S-TD-E or other -50V/-3A PNP transistors in the SC-62/PCP package. Verify that substitute parts maintain identical pin configurations and saturation voltage characteristics to ensure circuit compatibility without redesign.
