Thyristors belong to a family of electronic components called semiconductors. They are used to control a wide range of AC and DC electrical circuits, such as home appliances, industrial motors and drives, consumer electronics, telecommunications and automotive applications. The most common thyristor is the TRIAC or ‘Triode for Alternating Currents’.

TMA106S-L is a thyristor device that offers a high degree of input sensitivity within normal AC power supply ranges. It is primarily used in high voltage applications and is designed with an integrated high voltage MOV(Metal Oxide Varistor) for surge suppression and EMI (ElectroMagnetic Interference) noise reduction. It is also optimized for low on-state losses, low gate control power and prolonged turn-on and turn-off times.

The TMA106S-L operates in a very simple manner with a small delay time from when the gate receives a voltage to when the device activates. It also offers a positive temperature coefficient that will increase with increasing temperature, which reduces gate trigger current and therefore helps to reduce gate power consumption. In addition, the device has a low impedance level across its terminals which makes it easier to switch high currents and minimizes power losses.

The TMA106S-L is used in a variety of electrical applications due to its low cost, high efficiency, and low voltage requirements. It is most commonly used in power conditioning and motor control devices, such as AC and DC motor drives, AC and DC servo motors, and variable frequency drives that require high input sensitivity, low on-state losses, high temperature stability, and low gate power consumption. It is also used in AC and DC motor starters, as well as in applications that require a combination of surge suppression, EMI protection, and high current switching.

The working principle of the TMA106S-L can be explained in three stages. The first stage is when the gate receives a voltage and turns on the device. This is the turn-on stage where the main current is applied and the thyristor is switched on. In the second stage, the voltage applied to the gate is suddenly reduced, and the current is commutated away from the device, which stops the device from conducting and turns it off. Finally, at the third stage, the gate voltage is increased again, allowing the device to turn on again.

In conclusion, TMA106S-L is widely used in many different applications due to its low cost, high efficiency and low voltage requirements. It offers excellent solutions for motor control, power conditioning, surge suppression and EMI reduction applications. It is also very easy to use and its working principle is extremely simple.
