Additional Infomation About Product

The BD681 is a high-power NPN bipolar Darlington transistor manufactured by STMicroelectronics. It is rated for 100V, 4A, 40W and comes in a SOT32 package. It offers high current gain (hFE) through the use of two internally coupled transistors in one package, amplifying the current from the collector to the emitter. The Darlington configuration is often used when dealing with high voltage and current levels. This makes it an ideal choice for circuits such as power transistors, drivers or power switching applications.
