2SB1124T-TD-H

Single Bipolar Transistors Overview

The onsemi 2SB1124T-TD-H is a PNP epitaxial planar silicon transistor housed in the PCP (SC-62) surface-mount package. It features a maximum collector-emitter voltage of -50 V and a continuous collector current capacity of -3 A. The device utilizes FBET and MBIT processes to achieve low collector-to-emitter saturation voltage and fast switching speeds. Designed for high-current applications, it offers a wide safe operating area (ASO). Key electrical ratings include a collector-base voltage of -60 V, an emitter-base voltage of -6 V, and a maximum power dissipation of 500 mW at 25°C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TD-H' against official onsemi documentation to confirm tape-and-reel packaging and compliance status. Ensure the part number matches the exact ordering designation required for your bill of materials, as suffix variations may indicate different packaging or qualification levels. Cross-reference with the latest datasheet revision to confirm active status and any potential obsolescence notices.

Single Bipolar Transistors Selection Notes

Select this component for circuits requiring a PNP switch with moderate current handling and low saturation voltage. The PCP package suits space-constrained surface-mount designs. Evaluate thermal management requirements given the 500 mW power dissipation limit. Consider the -50 V voltage rating to ensure compatibility with system supply rails and transient conditions.

Single Bipolar Transistors Part Context

The 2SB1124 belongs to onsemi's family of low VCEsat bipolar transistors designed for high-efficiency switching. It is often paired with its NPN counterpart, the 2SD1624, in complementary configurations. The PCP package provides a compact footprint suitable for automated assembly in consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations

Officially documented substitutes include the 2SD1624 (NPN complement) and other devices within the 2SB1124 series such as 2SB1124S-TD-E. Verify pinout and electrical parameters match before substitution.
