TRIAC

TRIAC. Power control on alternating current (AC)

Triac is a semiconductor device that belongs to the family of thyristor control devices. It is essentially two SCR connected in parallel and backwards, sharing the same gate.

Zener diode - Basic Operation - Applications

Zener diode – Basic Operation – Applications

What is a Zener diode?

The Zener diode is a special type of diode that allows the flow of current on the opposite direction of the arrow of the diode. This diode does not conduct until the applied voltage reaches or is greater of the breakdown voltage. Zener diode is very popular as Voltage reference element.

What is a Schottky Diode? (Schottky Barrier Diode)

What is a Schottky Diode? (Schottky Barrier Diode)

What is a Schottky Diode? The Schottky diode or Schottky Barrier Diode unlike the semiconductor diode that has a P-N juntion, has an N-Metal junction. These diodes are characterized by their switching speed and low voltage drop when they are forward biased (typically 0.25 to 0.4 volts). Its symbol is showed on the following diagram. This diode works allmost like the […]

What is a Phototransistor? - Phototransistor Equivalent Circuit

What is a Phototransistor? – Phototransistor Equivalent Circuit

A phototransistor is essentially the same as a common transistor, but it can work in two different ways:

– As a common transistor, using the base current (IB)
– As a phototransistor, using the light that illuminates this element and that acts as the base current. (IP).
