BD677 Description

Short technical summary and product information.

The BD677 is a plastic medium-power silicon NPN Darlington transistor from On Semiconductor. It features a maximum collector-emitter voltage of 60V and a continuous collector current of 4A, with a DC current gain of at least 750 at 1.5A and 3V. The device dissipates up to 40W at a case temperature of 25°C. Designed for general-purpose amplifier applications, it can be used as an output device in complementary configurations. The transistor is housed in a TO-225AA/TO-126-3 through-hole package, with a junction-to-case thermal resistance of 3.13°C/W. It is Pb-Free and RoHS compliant. Operating temperature range is -55°C to 150°C.
