2SD2653KT146

Single Bipolar Transistors Overview

The 2SD2653KT146 is an NPN surface-mount bipolar junction transistor manufactured by ROHM Semiconductor. It utilizes a SOT-346-3 (SC-59) package with dimensions of 2.8x2.9mm and a thickness of 1.4mm. The device features a maximum collector current of 2A and a collector-emitter breakdown voltage of 12V. Key electrical parameters include a collector-base voltage of 15V, an emitter-base voltage of 6V, and a power dissipation rating of 200mW. The DC current gain ranges from 270 to 680 at VCE=2V and IC=200mA. The transition frequency is specified at 360MHz under identical conditions. Saturation voltage characteristics show a typical value of 90mV and a maximum of 180mV when driven with IC=1A and IB=50mA.

Single Bipolar Transistors Feature Summary

• Low saturation voltage design minimizes power loss during switching operations.
• High DC current gain provides efficient signal amplification capabilities.
• Compact surface-mount footprint supports automated assembly processes.

Single Bipolar Transistors Applications

• General purpose driver applications

Single Bipolar Transistors Procurement Notes

Verify the specific suffix KT146 to confirm the taping specification and reel quantity. Confirm RoHS compliance status for environmental regulations. Ensure storage temperature limits are respected to maintain device integrity. Check for automotive qualification restrictions as this component is not designated for vehicle use. Validate pinout alignment with the SC-59 standard before PCB integration.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high current handling within a small form factor. The low saturation voltage makes it suitable for battery-powered applications where efficiency is critical. Consider the 12V breakdown limit when designing for higher voltage rails. The high gain range reduces base drive requirements compared to standard transistors.

Single Bipolar Transistors Part Context

This part belongs to ROHM's Low VCE(sat) transistor series, designed for general-purpose switching and amplification. It replaces older through-hole technologies with a surface-mount solution. The SC-59 package is compatible with TO-236 standards, facilitating upgrades in compact consumer electronics and industrial control boards.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the 2SD2657KT146, which offers similar NPN characteristics but with a higher 30V collector-emitter voltage rating. Designers should verify that the increased voltage tolerance does not conflict with existing circuit constraints when swapping these models.
