The "Electronics" Department was founded on June 11, 1984 by order Number 975 of the Rector after the opening of the "Electronic Engineering and Microelectronics" specialty within the "Electrical Engineering, Electronics and Automation" faculty. Assoc. Prof. PhD Vasil Filipov Petrov was elected as its first head.

Heads of the "Electronics" department over the years have been:

1984–1992    -    Associate Professor Vasil Petrov, PhD;

1992–1998  -   Associate Professor Stoycho Psederski, PhD;

2020  – up to now  Associate Professor Anelia Manukova, PhD.

Until 2000, the Department of Electronics employed 25 teachers, of whom 2 were associate professors, 3 candidates of technical sciences, 2 candidates of physical and mathematical sciences, 4 full-time graduate students (now doctoral students), one part-time graduate student and one on a free graduate course. The number of students trained in the specialty "Electronics and Microelectronics" is about 100 for one course per year. In this year, some of the professors from the "Electronics" department formed a new department in the faculty.
