So here we are trying to understand whether we must put a freewheeling diode directly across the inductor in a boost converter or not, to safeguard the switching transistor? How Boost Converter Works So in a boost converter, we got one inductor, one power switch like a MOSFET, one diode and one output capacitor. Input […]

How to Calculate Zener Diode Resistor
In this article I have explained how to calculate and the find the value of the zener diode resistor using simple formulas. What is a Zener Diode Zener diodes are semiconductor devices which are used for regulating an input DC voltage to any desired output voltage. The regulated output voltage value directly depends on the […]
40A Diode with Reverse and Overvoltage Protection
In this post we study an outstanding high current diode which features not only an in-built reverse current protection but also an over-voltage protection for safeguarding sensitive electronic circuits against back emfs, transients and load dump occurrences. How 40 Amp Diode RBO40-40G/T Works The device RBO40-40G/T from STMicroelectronics comes in a TO-220 package and looks […]
Transistor Zener Diode Circuit for Handling High Current Stabilization
The high power “zener diode” circuit using transistor shunt regulator presented here can be used for obtaining a highly accurate, temperature and voltage stabilized outputs from high current sources, safely. Normal Zener Limitation The low power zener diodes that we normally use in electronic circuits are specified to work with low currents, and therefore cannot […]
What is a Gunn Diode? How it Works?
Gunn diodes are semiconductor devices which are used to generate low-power microwave signals in a simple and low-cost manner. These have been in use for more than 60 years now. Gunn diodes can work with frequencies ranging from a few gigahertz to over 100 GHz. It was first discovered by J. B. Gunn of IBM […]
Tunnel Diode – Working and Application Circuit
A tunnel diode is a type of semiconductor diode which features a negative resistance on account of a quantum mechanical effect known as tunneling. In this post I have explained the basic characteristics and working of tunnel diodes, and also a simple application circuit using this device. We will see how a tunnel diode could […]
