BD675AS Description

Short technical summary and product information.

The BD675AS is an NPN Darlington transistor manufactured by On Semiconductor. It is designed for general-purpose switching and amplification applications requiring high current gain. The Darlington configuration provides a minimum DC current gain (hFE) of 750 at Ic=2A, Vce=3V.

 

Key electrical ratings include a collector-emitter voltage (Vceo) of 45V, a continuous collector current (Ic) of 4A, and a maximum power dissipation of 40W. The collector-emitter saturation voltage (Vce(sat)) is typically 2.8V at Ib=40mA, Ic=2A. The device can operate at a junction temperature up to 150°C.

 

The transistor is housed in a TO-225AA / TO-126-3 through-hole package, suitable for PCB mounting. It is RoHS3 compliant and has a moisture sensitivity level of 1 (unlimited). The BD675AS is a reliable choice for medium-power switching and linear applications.
