There are some factors to consider in calculating MOSFET power dissipation. When the power dissipation is known, it is possible to compute the junction temperature of the MOSFET. Important to take that a MOSFET installed with no heatsink has different computation strategy compared to the one with a heatsink. Small current or low power MOSFETs are usually mounted to PCB

Two of the most common three terminal semiconductor nowadays are MOSFET and BJT. MOSFET is metal oxide semiconductor field effect transistor. It is a variant of FET. BJT on the other hand is bipolar junction transistor. It is worth to discuss MOSFET and BJT comparison to understand which part to use. Read below comparisons. 1. Application of MOSFET and BJT

It is very common application to drive a relay with a MOSFET. From household applications to automotive are using this circuit. There are some aspects to consider like the stress on the MOSFET, the level of driving voltage to guarantee MOSFET saturation, the level of the actual voltage applied to the relay coil if enough to meet the requirement and

Circuit breaker is the most common short circuit and over current protection. It is a simple electrical device but very important to safety. The most common question is what the current rating of the breaker will be to safely protect devices during abnormal condition. Basically, this is not the only thing to consider in selecting a circuit breaker. Below are

Buck Converter Basic Function Before going to buck converter design tutorial, we will discuss first how buck converter works in order to fully understand the following tutorial. A buck converter is a switching converter with a voltage output lower than voltage input. It is also called as a step-down switching converter. A buck converter has only four main parts. They

Diode is a two terminal semiconductor device. One terminal is called the anode while the other terminal is cathode. Anode needs a high potential while cathode needs a lower potential level for the diode to be forward biased. The term forward biased means the diode terminals are supplied with the right voltage level. When the diode is not supplied by

Transistor is an active electronic part. An active electronic part is something can perform amplifications or signal processing. Transistors are basic elements on power amplifiers, audio amplifiers, switching converters, power supplies and so on. A transistor term is somewhat generic. It could be a BJT, MOSFET of JFET. But for common people (electronic hobbyist), it is commonly referring to a

Relay is an electromechanical part though nowadays there is already a so-called solid-state relay. An electromechanical means a combination of electrical and mechanical actions or functions. For hobbyist, it is important how to know if a relay defective. But before going to that, let us discuss the basics of a relay for better understanding. As mentioned above, a relay is
