2SB1243TV2R

Single Bipolar Transistors Overview

The 2SB1243TV2R is a PNP silicon epitaxial planar power transistor rated for -60V collector-base voltage and -50V collector-emitter breakdown. It supports a continuous collector current of -3A with a maximum power dissipation of 1W in standard packaging, extending to 15W on a printed circuit board with adequate copper plating. The device features a minimum DC current gain (hFE) of 120 and a transition frequency of 70MHz. Its typical collector-emitter saturation voltage is -0.5V at -2A collector current.

Single Bipolar Transistors Procurement Notes

Verify the ordering suffix TV2R against the manufacturer's official datasheet to confirm the specific tape-and-reel quantity and hFE binning classification. Ensure the component matches the required polarity and package dimensions before integration into the design.

Single Bipolar Transistors Selection Notes

Select this component when a PNP power transistor with -60V rating and -3A current capacity is required. Consider its low saturation voltage for efficiency and verify compatibility with the intended NPN counterpart, such as the 2SD1760 or 2SD1864, for balanced push-pull configurations.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1184/2SB1243 series of medium-power PNP transistors manufactured by ROHM. It shares identical electrical characteristics with the 2SB1184 but differs in packaging and handling specifications defined by the ordering code.

Single Bipolar Transistors Replacement Considerations

The 2SB1184 serves as the direct electrical equivalent within the same series. For complementary NPN requirements, the 2SD1760 or 2SD1864 are specified as matching pairs.

Single Bipolar Transistors FAQ

What is the typical collector-emitter saturation voltage?

The typical VCE(sat) is -0.5V when measured at a collector current of -2A and base current of -0.2A.

Is this transistor suitable for automotive applications?

No, the documentation specifies that these products are intended for general-use electronic equipment and are not designed for radiation tolerance or automotive safety-critical systems.

How does the power dissipation change based on mounting?

Standard power dissipation is 1W, but it increases to 15W when mounted on a printed circuit board with 1.7mm thickness and collector copper plating of 100mm² or larger.
