Introduction

TVS (Thyristors) are a type of electronic device used in a wide range of applications such as power supplies, motor control, voltage regulation and lighting. They are particularly useful for controlling high voltages, magnitudes of current and transient states. The TISP4260H3LMR-S is a Thyristor from Toshiba, featuring an industry leading repetitive peak off-state voltage of 600V, high on-state current of 10A and maximum search junction temperature of 150°C. This article looks at the application field and working principle of the TISP4260H3LMR-S.

Application Field

The TISP4260H3LMR-S is ideal for applications that require high power handling and reliability. It’s well suited for controlling high voltages up to 600V without having to worry about potential breakdown, and has a maximum search junction temperature of 150°C which makes it suitable for long-term operating stability in an aggressive environment. The device is also optimized for high frequency operation, making it ideal for pulse width modulation (PWM) applications. Examples include switched mode power supplies, speed and direction control, AC drives and DC motors.

Working Principle

Thyristors are a type of semiconductor device that works on the principle of a voltage induced switch. When a voltage is applied to the gate of the device, a current will flow between the anode and cathode and the device will switch on. Once the voltage has been applied, it will continue to remain on and will only switch off when the voltage is removed. By keeping the gate voltage on, the device can be set to a reliable current carrying state which can be used for controlling high voltage and current levels.The TISP4260H3LMR-S works by using a voltage triggered gate that is capable of carrying up to 600V. When the gate voltage reaches a particular threshold, a current will flow between the anode and cathode and the device will switch on. The device is designed to maintain reliable on-state current regulation with an upper threshold of 10A, allowing it to remain in a controlled current state for a period of time.

Conclusion

The TISP4260H3LMR-S is a high power thyristor capable of controlling high voltages up to 600V with a maximum off-state voltage of 600V, high on-state current of 10A and maximum search junction temperature of 150°C. It is ideal for controlling high voltages and currents, and is suitable for applications that require reliable operation in an aggressive environment. The device is also optimized for high frequency operation, making it ideal for pulse width modulation applications.
