Category
The GOODWORK BCP56 is a cost-effective NPN BJT in SOT-223 package designed for low-power switching and amplification. With 100V VCEO, 1A Ic, and 250 hFE, it suits general-purpose control circuits and low-power motor drives. Key features include 100MHz transition frequency and 1.5W power dissipation. Thermal management requires heatsinks above 1W load. Applications include consumer electronics, automotive sensors, and power supplies. Strengths are cost efficiency and RoHS compliance, while limitations include moderate thermal performance and frequency range.
