Thyristors - SCRs

A Silicon Controlled Rectifier (SCR), or thyristor, is a solid-state semiconductor device with four layers of alternating P- and N-type materials. It was invented by a team of engineers led by Gordon Hall and Morton Heilig in 1957, and are used in various electronic applications. SCRs have many advantages over other semiconductor devices, such as their simple and efficient switching capabilities, low voltage drop, and high surge current capability.

12TTS08STRR Application Field and Working Principle

The 12TTS08STRR is a high voltage and high surge current thyristor, and is used in applications such as motor control, solenoid and relay control, speed or encoder control, and switch-mode power supplies. Its high surge current capability makes it suitable for applications with significant load changes. The 12TTS08STRR is also ideal for applications requiring high frequency operation, such as pulse-width modulation systems.

The 12TTS08STRR has a turn-on voltage of -6.0V, and can handle a surge current up to 1080A. It features a low operating voltage of 0.9V, making it suitable for low-power applications. The thyristor is diode-protected and available in both through-hole and surface-mount packages.

The 12TTS08STRR is typically used in applications where fast switching and high current capability is required. When the gate voltage is applied to the thyristor, it will start to conduct between the anode and cathode, allowing current to flow through the load. The gate voltage must be kept at a value greater than the turn-on voltage to maintain the anode-cathode conduction. When the gate voltage falls below the turn-off voltage, the thyristor will cease to conduct and no current can flows through the load.

The 12TTS08STRR is a versatile device, and can be used in both high voltage and high current applications. It is also ideal for applications requiring fast switching and high surge current capability. With its simple and efficient switching capabilities, low voltage drop, and high surge current capability, the 12TTS08STRR is a reliable and effective thyristor for a wide range of applications.
