2SB1123T-TD-EX

Single Bipolar Transistors Overview

The onsemi 2SB1123T-TD-EX is a PNP bipolar junction transistor (BJT) designed for high-density mounting in surface-mount applications. It utilizes FBET and MBIT processes to achieve low collector-to-emitter saturation voltage and fast switching speeds. The device supports a maximum continuous collector current of 2 A and a collector-emitter breakdown voltage of -50 V, with a power dissipation rating of 1.3 W. Packaged in the ultraminiature PCP format, it offers a wide safe operating area (ASO) and is suitable for use as a switch or amplifier in compact electronic circuits.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TD-EX' against official documentation to confirm tape-and-reel packaging details and compliance status. Ensure the component matches the PCP package outline and pin configuration required by the design. Cross-reference the manufacturer's latest datasheet for any updates regarding RoHS compliance or material declarations prior to final procurement.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a 50 V rating and 2 A current capability is required in a small surface-mount footprint. The low VCE(sat) makes it suitable for efficient switching applications where power loss must be minimized. Consider the PCP package dimensions for PCB layout constraints and ensure thermal management aligns with the 1.3 W dissipation limit in the intended environment.
