The BD678 is a plastic medium-power silicon PNP Darlington transistor from On Semiconductor, designed for use as output devices in complementary general-purpose amplifier applications. It features high DC current gain with a minimum hFE of 750 at IC=1.5A and VCE=3V, and monolithic construction. Key maximum ratings include a collector-emitter voltage (VCEO) of 60V, collector current (IC) of 4A, base current (IB) of 0.1A, and power dissipation (PD) of 40W at case temperature 25°C. The collector-emitter saturation voltage (VCE(sat)) is typically 2.5V max at IC=1.5A and IB=30mA. The device operates over a junction temperature range of -55°C to 150°C, with a thermal resistance junction-to-case of 3.13°C/W. The BD678 is offered in a through-hole TO-126 package (also TO-225AA) and is Pb-Free and RoHS compliant. It is complementary to NPN Darlington transistors BD675, BD675A, BD677, BD677A, BD679, BD679A, BD681, and is equivalent to MJE700, MJE701, MJE702, MJE703. This transistor is suitable for medium-power switching and linear amplification circuits.
