The MMDT3906SG with SOT-23-6 is a surface-mounted, Bipolar Junction Transistor (BJT) with RoHS compliance manufactured by Pingjingsemi. The devicecomes packaged in a surface mountable SOT-23-6 package and is made of Silicon MOSFET material. It is suited for Linear and Switching applications.It can be used in a wide range of applications including audio, video signal amplifications, general frequencies amplifiers, and digital ICs. The transistors have a collector to base voltage (VCBO) of 60V, collector current (IC) of 200mA, and a DC current gain (hFE) of 78. The package contains three elements, the base, collector and emitter. This device has an efficient operation due to its Epitaxial planar structure with diffused NPN design.
