Overview
The BC847BMTF is an NPN epitaxial silicon transistor produced by onsemi (formerly Fairchild Semiconductor). This component is part of the BC846/BC847/BC848/BC850 series and is designed for both switching and amplifier applications. It is packaged in a SOT-23 3L format, making it suitable for automatic insertion in thick and thin-film circuits. However, it is important to note that the BC847BMTF is currently obsolete and no longer manufactured, with recommended substitutes available.
