2SB1126-TD-E

Single Bipolar Transistors Overview

The onsemi 2SB1126-TD-E is a PNP bipolar junction transistor designed for surface-mount applications. It utilizes the PCP (SC-62) package, measuring 4.5 x 2.5 x 1.5 mm. The device supports a maximum DC collector current of 2 A and a collector-emitter voltage of 50 V. Key electrical ratings include a collector-base voltage of -60 V, an emitter-base voltage of -6 V, and a maximum power dissipation of 1.3 W. It features a single transistor configuration with three pins and operates at frequencies up to 150 MHz within a junction temperature range extending to +150 °C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix against official documentation to confirm pinout orientation and tape-and-reel specifications. Ensure the component matches the required thermal management capabilities for the intended PCB layout. Confirm compliance with relevant environmental directives if RoHS status is critical for the assembly process.

Single Bipolar Transistors Selection Notes

Select this component when a high-current PNP switch is required in a compact SMD form factor. The PCP package provides a balance between thermal performance and board space efficiency. Consider the 150 MHz frequency rating for general-purpose switching rather than high-frequency RF applications.

Single Bipolar Transistors Part Context

This part belongs to the 2SB112x series of bipolar transistors from onsemi. These devices are engineered for general-purpose switching and amplification tasks. The series shares common design principles focused on low saturation voltage and robust current handling within small outline packages suitable for automated surface-mount assembly.

Single Bipolar Transistors Replacement Considerations

The 2SB1124S-TD-E is a confirmed substitute within the same product family. Both parts share identical PCP packaging and similar electrical characteristics, including 50 V collector-emitter voltage and 2 A to 3 A current ratings. Verify pin compatibility before substitution.
