TISP4250H3BJR-S

TVS - Thyristors

The TISP4250H3BJR-S is a three-phase thyristor module from Infineon Technologies. It is a Single-Phase Module, allowing the low side of the circuit to be connected directly to the GND, while the high side is connected to the high voltage side, with a maximum of 600V. This thyristor has a high surge current rating of 15kA/600V, which makes it an ideal choice for applications requiring high peak current in the automotive and industrial sectors.

Application Field

The TISP4250H3BJR-S is a good solution for applications requiring high peak current, such as electric motor starters, motor drives, electric power steering, LED lighting and industrial automation systems. It can also be used in power supplies, solar inverters, HVAC systems, power window systems and battery chargers. Due to its rugged design, it is also suitable for applications in harsh or extreme environments, such as mining, construction, and oil and gas.

Working Principle

The TISP4250H3BJR-S thyristor module works on a simple principle. When a positive voltage is applied across the two power terminals, an electrical current is established and the thyristor is closed, allowing electricity to flow. As the current passes through the thyristor, the control circuit supplies energy to the gate circuit, which keeps the thyristor on. The gate current is maintained while the voltage is applied, and is automatically turned off as the voltage is removed. This allows the thyristor to remain in an open state until the current is applied again.

The TISP4250H3BJR-S thyristor module is a great solution for applications requiring high peak current. Its rugged design and high surge current rating make it suitable for a wide range of industrial and automotive applications.
