2SB1184TLP

Single Bipolar Transistors Overview

The ROHM Semiconductor 2SB1184TLP is a PNP silicon epitaxial planar power transistor designed for medium-power applications. It features a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) rating of -3 A. The device achieves a typical low collector-emitter saturation voltage (VCE(sat)) of -0.5 V at IC/IB = -2A/-0.2A. It operates within a junction temperature range of -55°C to +150°C and offers a DC current transfer ratio (hFE) ranging from 120 to 390 depending on the specific grade.

Single Bipolar Transistors Feature Summary

• Low collector-emitter saturation voltage for efficient switching
• Epitaxial planar structure for high reliability
• Complements NPN counterparts such as the 2SD1760 and 2SD1864

Single Bipolar Transistors Applications

• General-purpose amplification circuits
• Medium-power switching applications
• Audio visual equipment

Single Bipolar Transistors Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to confirm packaging specifications, such as tape-and-reel quantities or hFE binning classifications. Ensure that the component meets the required environmental standards and that the datasheet revision matches the intended design implementation.

Single Bipolar Transistors Selection Notes

Select this component when a PNP power transistor with a -50 V collector-emitter breakdown and -3 A continuous current capability is required. Consider the specific hFE classification (Q or R type) needed for the circuit's gain requirements. Verify thermal management capabilities based on the 1 W surface-mount dissipation rating.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1184 series of PNP silicon transistors manufactured by ROHM Semiconductor. It is specifically engineered as a complementary device to the 2SD1760 and 2SD1864 NPN transistors, allowing for matched performance in push-pull amplifier configurations and balanced switching pairs.

Single Bipolar Transistors Replacement Considerations

The 2SB1243 is an officially documented complementary counterpart within the same product family. Designers should verify pinout compatibility and electrical parameter alignment before substituting components in existing designs.
