The 2SD2654TLV is a general-purpose NPN silicon bipolar junction transistor manufactured by ROHM Semiconductor. It features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 150 mA. The device offers a high DC current gain ranging from 560 to 2700 depending on the classification rank, with a transition frequency of 250 MHz. Key electrical characteristics include a low collector-emitter saturation voltage of 300 mV at specified currents and an emitter-base breakdown voltage of 12 V. Power dissipation is rated at 150 mW, and it operates within a junction temperature range up to 150 °C.
Verify the specific hFE ranking (U, V, or W) required for your design, as the datasheet defines distinct gain ranges for each class. Confirm that the EMT3 package dimensions align with your PCB footprint. Ensure storage conditions remain within recommended humidity and temperature limits to maintain solderability before mounting.
Select this component when a small-signal NPN transistor with moderate voltage handling and high gain is needed. The 250 MHz transition frequency supports low-frequency amplification tasks. Consider the 150 mW power dissipation limit and derating requirements based on ambient operating temperatures during circuit design.
