2SB1243TV2Q

Single Bipolar Transistors Overview

The Rohm Semiconductor 2SB1243TV2Q is a PNP silicon epitaxial planar power transistor rated for -60V collector-base voltage and -50V collector-emitter voltage. It supports a continuous collector current of -3A with a maximum collector power dissipation of 1W at 25°C ambient temperature, rising to 15W when mounted on a heatsink at 25°C case temperature. The device features a typical low saturation voltage of -0.5V at -2A collector current and -0.2A base current. It offers a DC current gain range of 120 to 390 depending on the sub-type classification and a transition frequency up to 70MHz.

Single Bipolar Transistors Feature Summary

• Designed as a complementary pair to NPN transistors such as the 2SD1760 and 2SD1864

Single Bipolar Transistors Applications

• General-purpose audio visual equipment
• Office automation devices
• Communication devices
• Electronic appliances
• Amusement devices

Single Bipolar Transistors Procurement Notes

Verify the specific hFE bin (Q or R) required for your circuit design, as the datasheet classifies gain ranges separately. Confirm the TV2 packaging code corresponds to the 2500-piece tape and reel quantity needed for your assembly line. Ensure the SC-63 package dimensions align with your PCB footprint requirements before finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component for applications requiring a PNP power transistor with moderate current handling capabilities. The -60V rating suits general low-voltage power management tasks. Consider the thermal resistance limits when designing heat dissipation strategies, as the 15W rating requires specific mounting conditions on a printed circuit board with adequate copper plating.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1184/2SB1243 series from Rohm Semiconductor. Both models share identical absolute maximum ratings and structural specifications. The primary distinction lies in the DC current gain classification bins available within the product line. The TV2 suffix indicates the specific taping and reel packaging format used for automated surface-mount assembly processes.

Single Bipolar Transistors Replacement Considerations

The datasheet explicitly identifies the 2SD1760 and 2SD1864 as complementary NPN counterparts. No other direct substitute part numbers are documented in the provided source material. Verify pinout compatibility if considering alternative manufacturers, as the SC-63 package defines emitter, collector, and base arrangements.
