2SD2656T106

Single Bipolar Transistors Overview

The 2SD2656T106 is a single NPN silicon bipolar junction transistor manufactured by ROHM Semiconductor. It operates with a maximum collector-emitter voltage of 30 V and a continuous collector current of 1 A. The device features a transition frequency of 400 MHz and a power dissipation rating of 200 mW. It is housed in an SOT-323 (UMT3) surface-mount package. Key electrical parameters include a DC current gain ranging from 270 to 680 at 100 mA, a collector-emitter saturation voltage of 350 mV, and a maximum operating temperature of +150°C.

Single Bipolar Transistors Feature Summary

• High DC current gain for efficient signal amplification
• Automotive-grade reliability certified under AEC-Q101 standards
• Low collector-emitter saturation voltage for reduced power loss
• Compact SOT-323 surface-mount package for space-constrained designs

Single Bipolar Transistors Applications

• General-purpose switching circuits in automotive electronics
• Amplifier stages requiring high gain and moderate current
• Driver circuits for low-power loads in vehicle systems

Single Bipolar Transistors Procurement Notes

Verify the specific suffix T106 corresponds to the required tape-and-reel packaging configuration. Confirm AEC-Q101 qualification status if automotive compliance is mandatory. Ensure the SOT-323 footprint matches the target PCB layout. Cross-reference the datasheet for thermal derating curves relevant to the intended operating environment.

Single Bipolar Transistors Selection Notes

Select this component when a 30 V NPN transistor with 1 A capability is required in a compact SMD form factor. The high hFE range suits applications needing minimal base drive current. Consider the 200 mW power limit for thermal management. Verify that the 400 MHz bandwidth meets the signal frequency requirements of the design.

Single Bipolar Transistors Part Context

This part belongs to the 2SD2656 series of NPN transistors designed for general-purpose and automotive applications. It shares the UMT3/SOT-323 package with other variants in the family but differs in electrical ratings and packaging specifications. The T106 suffix denotes specific taping and reel dimensions defined by the manufacturer.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same series include 2SD2656FRAT106, which offers identical electrical characteristics and automotive certification in the same UMT3 package.
