2SD2226KT146W

Single Bipolar Transistors Overview

The 2SD2226KT146W is a general-purpose NPN bipolar junction transistor manufactured by Rohm Semiconductor. It features a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 150 mA. The device operates with a transition frequency (fT) of 250 MHz and a maximum power dissipation (PD) of 200 mW. DC current gain (hFE) ranges from 560 to 2700 depending on the rank, with a typical value of 250 MHz at 100 MHz. The saturation voltage (VCE(sat)) is 300 mV max at IC/IB=50/5mA.

Single Bipolar Transistors Feature Summary

• High DC current gain for efficient signal amplification
• Low saturation voltage for improved switching efficiency
• High emitter-base breakdown voltage capability

Single Bipolar Transistors Applications

• Low frequency amplifier circuits

Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank suffix (U, V, or W) required for your design's gain specifications before ordering. Confirm that the SMT3 package dimensions align with your PCB footprint. Ensure proper electrostatic discharge handling protocols are followed during storage and assembly to prevent damage to the sensitive semiconductor junction.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is needed for low-frequency applications. The 50V rating suits general-purpose switching and amplifying tasks. Consider the thermal derating requirements for the 200mW power dissipation limit in enclosed environments. Verify compatibility with standard surface-mount reflow soldering profiles.

Single Bipolar Transistors Part Context

This part belongs to the 2SD2226K series of general-purpose transistors. It utilizes the SMT3 (SOT-346) surface-mount package. The KT146W suffix indicates the specific taping code, reel size, and hFE gain classification (Rank W: 1200-2700). It is designed for use in consumer electronics and office automation equipment.

Single Bipolar Transistors Replacement Considerations

The 2SD2226KT146V is a documented substitute within the same family, differing primarily in the hFE gain ranking.
