BD677 Description

Short technical summary and product information.

The STMicroelectronics BD677 is a bipolar junction transistor (BJT) belonging to the NPN Darlington configuration. This component is designed for applications requiring high current gain and switching capabilities.

 

Key electrical specifications include a collector-emitter breakdown voltage of 60V and a maximum continuous collector current of 4A. The transistor can dissipate up to 40W of power. Its DC current gain (hFE) is a minimum of 750 at 1.5A and 3V. The saturation voltage (Vce Sat) is specified at a maximum of 2.5V at 30mA/1.5A, and 1.5V at 1.5A.

 

The BD677 operates at a maximum junction temperature of 150°C. It is housed in a through-hole package, specifically TO-225AA or TO-126-3, with the supplier device package identified as SOT-32-3. This mounting type is suitable for standard PCB assembly processes.

 

Environmental compliance includes RoHS3 status, REACH unaffected, and an MSL of 1. These attributes are important for manufacturing and regulatory considerations.
