TIC201D-S application field and working principle

Thyristors - TRIACs are types of switching semiconductor devices designed to control an AC power source in a circuit by turning the power source on and off continuously. TIC201D-S is an innovative medium power 3-quadrant TRIACs device offering the reliability, cost savings and convenience of a low current TRIAC. It uses a PNPN (Generation 4) chip design for improved stability and is compatible for use with three-phase and single-phase applications.

The TIC201D-S\' primary application is as a basic on/off switch for general lighting projects, like those found in commercial and residential settings. It can also be used to power larger equipment, such as air conditioning or heating units. The device has a zero voltage turn-on mode and one of the widest static on-state current ranges on the market, making it extremely versatile in a variety of applications.

The TIC201D-S is able to stay in conduction until the driver current is reversed. In this way, it acts as a "memory switch," retaining its previous on/off state after the control voltage is removed. The device is also able to handle a higher amount of peak current compared to other similar devices, making it useful in power cycling applications.

The operating principle of the TIC201D-S is based on the forward voltage bias of its gate terminal. When a positive pulse is applied to the gate terminal, a current is allowed across the P and N type regions, resulting in a voltage drop from anode to cathode. This generates a larger current flow from anode to cathode, which is referred to as "on" state. When a positive pulse is no longer applied, the current flow is limited to the leakage current of the chip, which is referred to as "off" state.

The TIC201D-S TRIAC offers an efficient, cost-effective and reliable solution for AC switching applications. It is able to provide fast switching and can handle a wide range of current and voltage levels, making it ideal for controlling medium to large loads. The device is also designed to remain in the same state after the control voltage is removed, ensuring consistent and reliable operation. The TIC201D-S is the perfect choice for commercial and residential lighting projects, as well as power cycling applications.
