2SB1240TV2P

Single Bipolar Transistors Overview

The 2SB1240TV2P is a PNP silicon epitaxial planar medium power transistor manufactured by ROHM Semiconductor. It features a collector-emitter voltage (VCEO) of -32 V and a continuous collector current (IC) of -2 A. The device has a maximum collector power dissipation of 1 W at 25°C on a printed circuit board with specific copper plating, or 10 W at 25°C case temperature. The DC current transfer ratio (hFE) ranges from 120 to 270 for the Q classification. Transition frequency (fT) is rated at 100 MHz under standard test conditions.

Single Bipolar Transistors Feature Summary

• Low collector-emitter saturation voltage (-0.5 V typical at IC/IB = -2A / -0.2A)
• Designed as a complementary pair to 2SD1758 and 2SD1862 NPN transistors
• Utilizes an epitaxial planar structure for robust switching performance

Single Bipolar Transistors Applications

• General-purpose switching circuits in audio visual equipment
• Office automation equipment driver stages
• Communication device signal processing
• Electronic appliance control logic

Single Bipolar Transistors Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to confirm package type and hFE binning. Confirm RoHS compliance status and check for any End-of-Life (EOL) notifications prior to finalizing procurement plans. Ensure the selected variant matches the required thermal dissipation constraints for the target application environment.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -32 V rating and -2 A current capacity is required. Consider the low saturation voltage for efficient switching applications. Verify that the thermal management design accommodates the specified power dissipation limits. Ensure the hFE gain range aligns with the base drive requirements of the circuit design.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1182/2SB1240 series of medium power transistors from ROHM. The TV2P suffix indicates a specific tape-and-reel packaging configuration with a quantity of 2500 units per reel. The device shares electrical characteristics with the 2SB1182 but differs in physical package dimensions and pinout orientation.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the 2SB1182 series devices. Cross-manufacturer alternatives should be evaluated based on matching VCEO, IC ratings, and package footprint compatibility.
