Characteristics of the Diode Zener diode, Photo, and Other types of Diode-when we talk about electronic components, certainly it will never be separated from the name of a component of a diode. Yes, because the component we can find in almost any type of electronic circuit either simple or complex.
A diode is an electronic component that is made of a semiconductor material. Component has the function as a diode rectifier electric current. Principle, the diode will conduct electric current to one direction, and inhibits electric current towards the opposite direction. In addition the diodes also have functions as a safety, voltage regulators, frequency control, etc.
To understand more about the components of the diode, then you should know how the characteristics of the diode itself. In order to know the characteristics of a diode, then we should do an experiment with how to connect the diode component to the power supply and also component resistor in series.
Diode Characteristics
So we'll find out how diode voltage variations the voltage source is given. As has been said above that the diodes have the properties of semiconductors. Diodes have two electrodes i.e. anode and cathode. In order to clarify the understanding of the characteristics of a diode, refer to the following figure.
Judging from the pictures above, the curve characteristics of the diode is obtained by measuring the voltage diodes (Vab) and the current through the diode (ID). When the anode is at a higher voltage than the cathode (positive VD), then it could be said to be a diode forward biased gets or can move forward. Conversely if the VD is negative, then the diode reverse bias gets aka biased backwards.
In addition if the value VDD modified, then the current ID and also the VD will also join the change. If seen from the function, the diode is divided into several types ranging from a diode connection, contact point, LED diodes, photo diode, diode zener diode, variable Capacitance to the diode bridge. The diode has a characteristic voltage flow relationships in large amounts, but only unidirectional.
In contrast to the contact point, usually a diode is used to change the frequency from high to low. While the LED is the kind of dioada that emit light when given a forward bias. A lot of people who think the same between LEDs and photo diode. When both types of diodes are different.
Photo diodes or diode photo will generate electricity when exposed to light. And the magnitude of the electric current generated by the photo diode depending on how much light is received. And for the type of the variable capacitance varactor diodes or will function as capacitors when installed in reverse.
Variable capacitance diodes are also widely used on an FM modulator and also on the VCO in the PLL. While the diode bridge is often used in a series of power supply as a rectifier. One more type of diode that is not less important is the zener diodes have a limiting characteristics as voltage and has a function as a voltage stabilizer aka voltage regulator.
That was the last bit of explanation about the characteristics of the diode zener diode, photo start diodes, LED, diode bridge, and many more others. With the information above, hopefully can add insight the reader everything related the world of electronics, especially concerning the electronic component called a diode. See you and please share this info to friends.
