Thyristors - TRIACs

A TRIAC (triode for alternating current) is a thyristor device that is widely used for controlling AC power across many different applications. It is a three-terminal semiconductor device with three layers of alternating P- and N-type materials. There are several advantages to using a TRIAC over other AC controlling methods, such as an SCR, such as its capability of controlling large currents and offer two logic states.L0103NE is a popular thyristor that acts as a TRIAC. It is an integrated, three-phase device and has a main control terminal and two auxiliary terminals. This device is mainly used to switch, phase-control, and phase-regulate ac loads. This device has various features, such as low RMS on-state resistance package, which ensures low power losses in operation. In addition, it has high surge current capability, which prevents the TRIAC from being damaged due to a huge surge in current.

L0103NE Application Fields

The most common application of L0103NE is in AC phase control circuits, where the load needs to be cyclically adjusted or dimmed, or when the current needs to be regulated, like in diode AC rectifiers. It also finds applications in motor speed control, lighting control, and even home appliances. This device is also used in high voltage AC switch control, like in current transformers, motor control switches, and so on.

L0103NE Working Principle

The working principle of L0103NE is based on the fact that a TRIAC consists of two SCRs connected in opposite directions. It operates by firing the two SCRs alternatively, so that when one SCR is gated, the current flows through both, allowing the load current to pass. During the duration that the current is flowing, the TRIAC remains in a conducting condition, and the firing angles can be controlled, depending on the gate pulse.When a positive gate signal with a sufficient voltage level, such as 400V, is supplied to the gate of the L0103NE, it triggers the SCRs and the current flows. When the negative gate signal is applied, the SCRs are deactivated, and the TRIAC conducts for the duration of the cycle depending on the firing angle. The control of the firing angle is achieved by changing the duration of the applied pulses.

Conclusion

The L0103NE is a cost effective Thyristor that is widely used in various AC phase control applications. Thanks to its low RMS on-state resistance package and high surge current capability, this device offers a high level of efficiency and reliability. As such, it finds applicability in various industrial and household applications, such as motor control, current transformers, and so on. In addition, this device is optimized for use in commercial and industrial circuits, and can be easily used in a variety of applications.
