2SC2411KT146R

Single Bipolar Transistors Overview

The 2SC2411KT146R is a medium power NPN bipolar junction transistor manufactured by Rohm Semiconductor. It features a collector-emitter voltage (VCEO) of 32 V and a maximum collector current (IC) of 500 mA. The device has a power dissipation rating of 200 mW and operates within a junction temperature range of -55 °C to +150 °C. Electrical characteristics include a DC current gain (hFE) ranging from 82 to 390 depending on the rank, a transition frequency (fT) of 250 MHz, and a collector-emitter saturation voltage (VCE(sat)) of 600 mV at IC=500mA. It is housed in an SMT3 (SOT-346/TO-236) surface-mount package.

Single Bipolar Transistors Feature Summary

• High collector current capability of 500 mA for medium power applications
• Low collector-emitter saturation voltage optimized for low voltage operation
• Surface mount design in compact SMT3 package for space-saving integration

Single Bipolar Transistors Applications

• Driving circuits
• Low frequency amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (P, Q, or R) required for the application, as gain varies significantly between classifications. Confirm that the SMT3 package dimensions align with the target PCB footprint. Ensure the operating environment stays within the specified thermal limits to maintain reliability. Check for any RoHS compliance documentation if environmental regulations apply to the final assembly.

Single Bipolar Transistors Selection Notes

Select this component when a 32V NPN transistor with 500mA capacity is needed in a small surface-mount form factor. It serves as a complement to the 2SA1036K PNP counterpart. Consider the hFE binning requirements carefully, as the minimum gain starts at 82. The device is suitable for general-purpose switching and amplification where moderate speed and power are sufficient.

Single Bipolar Transistors Part Context

This part belongs to Rohm's medium power transistor lineup, designed for standard electronic equipment. The KT146 suffix indicates the taping code and reel specifications for automated surface-mount assembly. It is distinct from higher-voltage variants like the 2SC2412 or lower-current high-frequency types like the 2SC3838.

Single Bipolar Transistors Replacement Considerations

The datasheet explicitly states it complements the 2SA1036K. For direct substitution, verify pinout compatibility and ensure the replacement meets the 32V/500mA/200mW ratings. Cross-reference with distributors for equivalent SOT-346 NPN transistors if Rohm supply is unavailable.
