Is zener a diode?
A Zener diode is a silicon semiconductor device that permits current to flow in either a forward or reverse direction. The diode consists of a special, heavily doped p-n junction, designed to conduct in the reverse direction when a certain specified voltage is reached.
What is pn junction diode?
A p-n junction diode is two-terminal or two-electrode semiconductor device, which allows the electric current in only one direction while blocks the electric current in opposite or reverse direction. The p-n junction diode is made from the semiconductor materials such as silicon, germanium, and gallium arsenide.
What is VI characteristics of Zener diode?
V-I characteristics of Zener diode initially a small reverse saturation current Io flows across the diode. As the reverse voltage is increased, at a certain value of reverse voltage, the junction will be breakdown and drastically a large reverse current flow through the device. This breakdown is called Zener breakdown.
How do I download SPICE models?
From the main page, click on Technical Support, and then click on Design Support/Design Simulation Models. The following page appears; upon searching on products and product categories and then clicking on the relevant part number, the SPICE model and an evaluation circuit can be downloaded.
What is a PSpice model?
PSpice is a high performance SPICE simulator that is used in combination with OrCAD Capture to simplify the design and testing of both analog and mixed signal circuits. The software is sold and maintained by Cadence Design Systems. Included in PSpice is a limited library of Coilcraft RF inductor models.
What is Zener diode?
How is the Zener diode used in PSpice?
1. First, choose the Zener diode voltage. It is the voltage value where the Zener diode will act as a close circuit and protect the load from overvoltage. For the above example in Pspice, the Zener voltage is 6.8V. There will be some situations where the targeted Zener diode voltage is not available.
What are the voltage levels of Zener diodes?
Over-Voltage Protection Circuit using Zener Diodes Every circuit design operates at different voltage levels, the most common voltage levels for a digital circuit are 3.3V, 5V, and 12V. But every design is unique and it is also common for a circuit to have more than one operating voltage.
Which is the best diode for over voltage protection?
A very common and cost-effective solution is to use a Zener Diode Over Voltage Protection Circuit. Zener Diodes – Basics Zener diodes are mostly the first choice to protect the circuit from an overvoltage condition. A Zener diode follows the same principle of the diode, which is blocking the flow of current in the reverse direction.
How are diodes described in a SPICE model?
Diodes are described in SPICE by a diode component statement referring to .model statement. The .model statement contains parameters describing the diode. If parameters are not provided, the model takes on default values.
