Thyristors, or thyristor devices, are semiconductor switching devices based on four-layer semiconductors such as silicon. Due to their low costs and simple design, thyristors have become the most reliable source of voltage and current controlling. This makes them the ideal choice for a wide range of industrial applications.

The TISP4070H3LMFR-S is an advanced thyristor device developed to provide reliable overvoltage and overcurrent protection for electronic equipment such as computers, telecommunications devices and control systems. The device consists of an integrated Silicon Controlled Rectifier (SCR) with a lateral MOSFET acting as the main protection element. The thyristor is constructed with a 40A gate drive signal, 4kV isolation voltage and a wide operating temperature range. It is manufactured with an inovative, low-cost, ultra-thin process technology.

Application Fields:

The most common application fields for the TISP4070H3LMFR-S are electronic safety systems, overcurrent protection, and surge protection. Its high surge capability makes it suitable for use in power supplies, UPS systems, and motor control systems as well.

The TISP4070H3LMFR-S is also suitable for use in high-frequency switching applications where precision control is required. Examples of such applications include motor speed controllers, digital input-outputs, and digital circuit control systems.

Working Principle:

The working principle of the TISP4070H3LMFR-S is based on a silicon-controlled rectifier (SCR) controlled by an external gate voltage. When the gate voltage increases to a certain level, the SCR is turned on to allow current flow across it. As soon as the current exceeds the device\'s rated current, the SCR will turn off itself to protect the system from damage. This reduces the amount of voltage and current that is consumed, thus making it an ideal choice for applications needing precise control.

The device also provides enhanced safety features such as temperature compensation and thermal overload protection. The temperature compensation feature is particularly important when using the device in high-temperature environments, as it helps to prevent excessive current flow in such conditions. The thermal overload protection prevents damage from high current flow by automatically tripping the device when an overload occurs.

The TISP4070H3LMFR-S is easy to install and maintain, offering the user complete control over the device\'s operation. The device is manufactured with an ultra-thin, low-cost process technology, highly energy efficient, making it an ideal choice for applications searching for precision control, reliable performance, and maximum safety.
