The diac is a two-terminal device having a combination of parallel-inverse semiconductor layers, which allows the device to be triggered through both directions regardless of the supply polarity. Diac Characteristics The characteristics of a typical diac can be seen in the following Figure, which distinctly reveals the presence of a breakover voltage in across both […]

Understanding MOSFET Safe Operating Area or SOA
If you are wondering or worried about precisely how much power your MOSFET can tolerate under extreme conditions, or under extreme dissipative situations, then the SOA figures of the device is exactly what you should be looking at. In this post we will be comprehensively discussing the Safe Operating Area, or the SOA, as it […]
12 Basic Digital Logic Circuits Explored
In the following paragraphs I will try to explain the most basic foundations of digital electronic circuits: namely logic gates and logic flip-flops. Whether it is a complex and larger digital circuits, or as simple as a BCD counter, for example the 7490, or a large-scale integration (LSI) microprocessor chip, eventually all of these comprise […]
Understanding MOSFET Current Rating in Datasheets
In this post I will comprehensively explain the current rating of MOSFETs in their datasheets, and helps us to understand how it is calculated by the design engineers, keeping in mind the various external parameters, which potentially impact the current limitations of the device. In simple terms, MOSFET current rating can be defined as the […]
6 Simple AC Bridge Circuits Explained
An AC bridge is a circuit which can be used for measuring parameters like capacitance, resistance, Inductance using differential method, by comparing them with known values of similar components, positioned diagonally across a bridge circuit, and through an analogue meter placed at the center of the bridge. Before we begin talking about the AC bridge […]
Understanding MOSFET Avalanche Rating, Testing and Protection
In this post I have explained MOSFET avalanche ratings, and learn how to understand this rating in the datasheet correctly, how the parameter is tested by the manufacturer, and measures to protect MOSFETs from this phenomenon. The avalanche parameter not only helps to verify the devices ruggedness, it additionally helps filtering out weaker MOSFETs or […]
