Thyristors - TRIACs can be used to solve challenges in controlling and switching of both AC and DC current. The L2008V8 is one such thyristor of the Triode for Alternating Current (TRIAC) family that can switch high voltages and higher currents. This device supports an efficient way in controlling and managing AC power distribution.

Features

L2008V8 TRIAC helps in limiting the total amount of power that is consumed in various applications. It has a bidirectional, symmetrical and three-terminal switch that works in the AC power supply. It consists of three main terminals namely MT1, M2 and MT2 for gate, main terminal 1 and main terminal 2 respectively. It has a power dissipation capacity between 500 to 800 (Vce)mW.

Applications and Working Principle

L2008V8 provides various applications and solutions for controlling and managing the AC current. It is used to switch and control both inductive and resistive loads. It can be connected in high side switch application, relay controls, automotive electronics and AC power control circuits. The TRIACs has high control reliability and works on a single firing signal which is especially used in applications that require low noise and energy saving characteristics.

The working principle of this thyristor is based on the AC voltage variation. The TRIAC will be triggered when the voltage reaches to a certain threshold voltage and it will be set in the “on” state. In this process, the gate current flows through the gate terminal and the main anode voltage will rise until the TRIAC is turned off (breakover point). This turn-on process of L2008V8 is known as “Triggering” or “Firing” and will be repeated every cycle until it reaches the peak load. After the peak load, the TRIAC will be turned off (breakover point) and this is known as “Re-triggering”. The switching cycle will then be repeated until the AC power is terminated.

L2008V8 TRIAC can also be used in switching applications where a periodical firing signal is necessary. The basic objectives of these applications are to switch on or off the AC power and to control the amount of current supplied in the circuit. Additionally, the thyristor helps to reduce the total amount of energy consumed as compared to a traditional mechanical switch. In addition to this, the device can be easily controlled by the frequency or amplitude of the triggering voltage.

In conclusion, the L2008V8 is an efficient, robust and reliable thyristor that can be used for controlling and managing the AC power. It can be used in a variety of applications such as switching applications, relay controls, high side switch application and AC power control circuits. The TRIAC is perfect for applications that require noise-free, energy-saving characteristics since it has a single firing signal.
