Diode Troubleshooting

How to Know a Defective Diode

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

Capacitor as ESD Protection

    Electrostatic discharge or simply ESD is a universal problem in electronic circuits. Capacitor as ESD protection is providing economical solution to the problem. I used to work in automotive electronics and we used high frequency capacitors to protect the exposed pins of our product. Exposed pins are the one accessible to users. There are several ways to protect

Transistor Operation Mode Determination

Transistor operation mode is can easily be determined by using mathematical equations. Don’t worry; these are not difficult equations. There are three operation modes to operate the transistor. These are cut-off, saturation and linear. In cut-off, the transistor is simply not conducting; so it is not a problem to send the transistor in this region. You can simply do that

MOSFET RDSon Temperature Coefficient Usage and Interpretation

MOSFET RDSon temperature coefficient is positive. Meaning, it will increase with increasing temperature. In this article I will discuss and interpret MOSFET RDSon temperature coefficient that is often given in the form of graph in datasheets like below. Datasheets may also provide actual RDSon data with respect to junction temperature instead of the coefficient like below. Datasheets also provides tabular
