2SB1184TLR

Single Bipolar Transistors Overview

The ROHM 2SB1184TLR is a PNP silicon epitaxial planar power transistor housed in the CPT3 (TO-252) surface-mount package. It provides a collector-emitter voltage of -50V and a continuous collector current of -3A, with a maximum collector power dissipation of 1W at 25°C ambient temperature. The device features a typical low saturation voltage of -0.5V at an IC/IB ratio of -2A/-0.2A. DC current gain ranges from 120 to 270 for the Q grade. It serves as a direct complement to the 2SD1760 and 2SD1864 NPN transistors.

Single Bipolar Transistors Procurement Notes

Verify the exact ordering suffix against official documentation to confirm packaging specifications. Confirm that the component meets RoHS standards if required by your manufacturing process. Ensure the supply status aligns with your production timeline, as availability may vary. Cross-reference the datasheet revision date to ensure you are using the most current electrical characteristics and absolute maximum ratings.

Single Bipolar Transistors Selection Notes

Select this component when a PNP power transistor with a -50V rating and -3A current capacity is required. Consider its low saturation voltage for applications demanding minimal power loss during conduction. Verify that the thermal management design supports the specified 1W power dissipation limit at the intended operating ambient temperature. Ensure the circuit requirements match the hFE classification available for the specific order code.

Single Bipolar Transistors Part Context

This part belongs to ROHM's lineup of general-use power transistors designed for standard electronic equipment. It utilizes a plastic encapsulated TO-252 package suitable for surface mounting. The device is engineered for use in consumer electronics and office automation rather than automotive or high-reliability safety-critical systems.

Single Bipolar Transistors Replacement Considerations

The 2SB1243 is listed as a similar level part with the same pinout and package. It offers a higher collector-emitter breakdown voltage of -60V compared to the -50V of the 2SB1184. Both parts share identical physical dimensions and terminal configurations.
