Thyristors are a type of solid-state switch typically used in conjunction with high-voltage and low-current loads such as motors. They are generally made with an active element that controls the conduction and the non-conduction state of the device. The TISP4072F3LMR-S is an automotive thyristors developed by Infineon Technologies. This particular model is a lead-free, medium power switching thyristor designed for use in automotive applications.

Application Fields

The TISP4072F3LMR-S is intended for use in automotive applications such as electric or hybrid vehicles where the need for high voltage switching reliability is required. This thyristor can be used to control the power flow to motors or other electrical loads. The TISP4072F3LMR-S is suitable for applications ranging from underhood, cabin, and body electronics in automobiles. It is also suitable for applications where reverse polarity protection is needed to prevent any damage from incorrect wiring.

Working Principle

Thyristors are controlled current devices that require an anode-cathode voltage to be present to "fire" and thus turn the device on. The TISP4072F3LMR-S has an off-state voltage rating of 600V, and a maximum on-state current of 450A. This device is designed to have a low turn-on time and minimal turn-off time, due to its high switching speed. It features a built-in temperature sensing circuit which senses the temperature of the device\'s junction and limits the maximum on-state current, thus protecting the device from overheating.

The TISP4072F3LMR-S has a reverse polarity protection capability, which protects the device from the damaging effects of any reverse wiring or battery connections. Its over-voltage protection capability prevents any surge voltages from being applied to the device. Its low-inductance design also makes it suitable for use in applications where fast switching speeds are required.

Conclusion

The TISP4072F3LMR-S is a high voltage, lead-free switching thyristor by Infineon Technologies. It is suitable for use in automotive applications, and features the capabilities of reverse polarity protection, over-voltage protection, and temperature sensing. Its low-inductance design allows for a fast switching speed, making it suitable for use in high-speed applications.
