SURGE PROTECTION CIRCUIT PRINCIPLE and DESIGN

Surge protection circuit is the one referred by many as protector for voltage spikes in AC grid lines; however it

Basic NPN Transistor Principles Universities are covering this topic very well but despite I still attempt to discuss NPN transistor

Electrostatic discharge or simply ESD is a universal problem in electronic circuits. Capacitor as ESD protection is providing economical solution

Transistor operation mode is can easily be determined by using mathematical equations. Don’t worry; these are not difficult equations. There

For power devices like power MOSFETs, power BJT and power diodes, heat sink is very important to provide thermal relief.

MOSFET RDSon temperature coefficient is positive. Meaning, it will increase with increasing temperature. In this article I will discuss and

In this article I will discuss the feature of the NPN transistor biasing tool and checker in excel that I

The most common application of Optocoupler is signal isolation. It provides complete isolation because its input side is not electrically

In optocoupler, CTR stands for current transfer ratio. This is comparable to the current gain beta in BJT. This is

When you already heard about Optocoupler devices, you may be heard also about CTR. CTR stands for current transfer ratio.
