BD675C Darlington Transistor TO-126-3

BD675C Darlington Transistor TO-126-3

This BD675C Darlington Transistor TO-126-3 is a single NPN plastic power Darlington device designed for high-current, high-voltage applications. It features a maximum collector-emitter voltage of 45 V and supports continuous collector currents up to 4 A, with a DC current gain of 750 at 1.5 A. Its low saturation voltage (2.5 V at 1.5 A) and robust thermal performance—1.25 W dissipation at 25 °C ambient or 40 W at case temperature—ensure reliable operation in demanding environments, with junction-to-case thermal resistance of 3.13 °C/W and junction-to-ambient of 100 °C/W.

Features
