Thyristors - TRIACs

A TRIAC, or Thyristor for Alternating Current, is an important device used to control the flow of electricity in an electrical circuit. It is a three-terminal solid-state device that, in its simplest form, performs the same function as a pair of back-to-back silicon controlled rectifiers (SCRs). A TRIAC is a semiconductor device consisting of three alternating current (AC) terminals: the anode and the two gate terminals (G1 and G2). While SCRs can pass current in only one direction, TRIACs can switch on and off in both polarities. TRIACs are commonly used in applications such as motor speed control, power supply, industrial heat controller, and automotive lighting.The T810-800B-TR is an eight-terminal thyristor designed for controlling AC loads up to 400 amps in automotive applications such as fuel injection systems, interior and exterior lighting, and wiper/washer motors. It is designed for use in a low voltage environment of up to 10 volts and features a 160°C junction temperature limit. The T810-800B-TR is a glass enclosed, hermetically sealed device with a lead-frame construction that enables high power transfer and low thermal resistance.The T810-800B-TR operates on a basic working principle, allowing DC to AC conversion and all related current control capabilities. As a bistable, or "latch-on", device, the TRIAC must first be "triggered" on by a high current pulse applied to the G1 and G2 terminals. Once triggered, the T810-800B-TR is held in a “buffer zone” between off and on, allowing it to control the current flow as long as energy is present in the circuit. This enables it to regulate AC voltage and current, and to cycle the current load at a specific frequency.The T810-800B-TR can be used in a variety of automotive applications where the need for active current control exists. This device is ideal for controlling DC power applied to AC loads, such as fuel injectors and lighting. It is also suitable for motor speed control applications, where its ability to cycle current at specific frequencies can provide precise speed regulation. The device can be used to regulate the current of HVAC systems for temperature control, such as used in commercial buildings and industrial heating and cooling. In addition, the device is ideal for automotive engine speed and transmission control applications, where it can provide precise current regulation and cycling during gear changeover.The T810-800B-TR is an effective and reliable device which provides the necessary current control characteristics required by many AC applications. Its small footprint and high current capability make it an ideal choice for space-constraint automotive applications. With its hermetically-sealed package, it ensures that all components remain dust- and moisture-free, allowing it to operate reliably under extreme environmental conditions.In summary, the T810-800B-TR is an effective, reliable and space-saving TRIAC suitable for a number of automotive AC applications, such as motor speed and gear control, HVAC, and fuel injection. With its high current capabilities and hermetically-sealed outer package, it can easily withstand temperature fluctuations and dust or moisture contamination, providing a reliable and cost-effective control solution for automotive applications.
