The BD681G is a plastic medium-power silicon NPN Darlington transistor from onsemi, designed for general-purpose amplifier and switching applications. It features a high DC current gain (minimum hFE of 750 at 1.5A collector current and 3V VCE) and monolithic construction for reliability.
Key electrical ratings include a maximum collector-emitter voltage (VCEO) of 100V, collector current (IC) of 4A, base current (IB) of 1A, and power dissipation of 40W at case temperature 25°C. 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 transistor is housed in a through-hole TO-126 package (also referred to as TO-225AA), which is suitable for medium-power designs. It is complementary to the PNP Darlington type BD682 and is Pb-free and RoHS compliant.
