2SCR544R

Single Bipolar Transistors Overview

The Diotec Semiconductor 2SCR544R is a high-current NPN transistor designed for surface-mount applications. It features an 80 V collector-emitter voltage rating and supports a continuous DC collector current of 2.5 A, with peak currents reaching 5 A. The device offers a DC current gain (hFE) ranging from 120 to 390 at 100 mA. Key electrical characteristics include a low collector-emitter saturation voltage of approximately 0.1 V and a transition frequency (fT) up to 280 MHz. Power dissipation capabilities are rated at 1000 mW on ceramic substrates or 500 mW on standard PCBs. The component operates within a junction temperature range of -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix when ordering, as variants like -Q and -AQ denote AEC-Q101 compliance or qualification respectively. Confirm package availability in SOT-23 or TO-236 formats based on board space constraints. Ensure thermal management aligns with the specified power dissipation limits under your operating ambient conditions. Cross-reference marking codes such as NS or HS to validate authenticity upon receipt.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring robust NPN switching with minimal voltage drop. Evaluate thermal resistance requirements carefully, as power dissipation drops significantly above certain ambient temperatures. Consider the complementary PNP type 2SAR544R if push-pull configurations are needed. Verify that the required hFE bin matches your circuit's base drive capabilities.
