Q4008LTTP

Thyristors - TRIACs

A TRIAC is a three-terminal semiconductor device, constructed using a base layer of n-type semiconductor material, surrounded by two layers of p-type material. It is used as a switch in many electronic circuits. The Q4008LTTP is a 400V, 8A TRIAC, meaning it is designed to switch up to 8A of current at a voltage of 400V.

Application Field

The Q4008LTTP is a silicon controlled rectifier (SCR) combined with two diodes that can be used as an efficient switch in many applications. It can be used for switching motors, lighting, heating elements and other circuits. Its high voltage capacity also makes it suitable for use in high voltage circuits. It can be used for AC switching with excellent resistance to surge currents. It has low on-state voltage drop and fast switching, which makes it suitable for many applications.

Working Principle

The TRIAC works by controlling the flow of current between two contacts. When the TRIAC is triggered, current flows through its base layer, creating a flow of current between the two p-type layers. This causes the current to flow between the contacts, resulting in switching of the TRIAC. The TRIAC will switch off when the current decreases and the control voltage is removed. The TRIAC can also be used to control the current and the on/off time of the device.

The Q4008LTTP is a robust and reliable device, making it suitable for use in many applications. It provides excellent current and voltage handling capability, making it suitable for use in a wide variety of circuits. It is also relatively inexpensive, making it a popular choice for many applications.
