2SB1240TV2R

Single Bipolar Transistors Overview

The 2SB1240TV2R is a PNP silicon epitaxial planar transistor manufactured by ROHM. It features a collector-emitter breakdown voltage of -32V and a maximum DC collector current of -2A. The device dissipates up to 10W at 25°C case temperature and operates within a junction temperature range of -55°C to 150°C. It utilizes the ATV (TO-220AB) package with three terminals. Electrical characteristics include a minimum DC current gain (hFE) of 120, a typical saturation voltage of -0.5V at specified currents, and a transition frequency of 100MHz.

Single Bipolar Transistors Feature Summary

• Low collector-emitter saturation voltage for efficient switching performance
• Designed as a complementary pair to NPN transistors such as the 2SD1758 and 2SD1862

Single Bipolar Transistors Applications

• General-purpose electronic equipment
• Audio visual equipment
• Office automation equipment
• Communication devices
• Electronic appliances

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix TV2R against official ROHM documentation to confirm the ATV package type and hFE binning classification. Ensure that the component meets RoHS compliance standards required for your manufacturing process. Confirm availability status as older revisions may have limited supply or be subject to replacement by newer equivalents.

Single Bipolar Transistors Selection Notes

Select this component when a medium-power PNP transistor with a -32V rating and -2A current capacity is required. Consider its low saturation voltage for applications demanding minimal power loss during conduction. Verify that the thermal dissipation requirements align with the 10W limit under appropriate heat sinking conditions. Ensure compatibility with existing circuit designs utilizing complementary NPN pairs like the 2SD1758.
