BD675C Darlington Transistor TO-126-3

Description

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 High collector-emitter voltage rating of 45 V. Supports continuous collector current up to 4 A. DC current gain (h FE ) of 750 at I C = 1.5 A, V CE = 3 V. Low saturation voltage V CE (sat) ≤ 2.5 V at I C = 1.5 A, I B = 6 mA. Wide operating junction temperature range from –55 °C to +150 °C. High power dissipation: 1.25 W at Ta = 25 °C; 40 W at Tc = 25 °C. Thermal resistance R th(j-c) = 3.13 °C/W; R th(j-a) = 100 °C/W. Standard TO-126-3 plastic package for easy PCB mounting.
