Thyristors are a type of electronic switch which control the current flow through a circuit. The Thyristor is also often referred to as a TRIAC, due to its three terminals which correspond to its acronym (Thyristor Rectifier Integrated Asymmetric Component). The T1235T-8T is a type of Thyristor which is typically used in the lighting and power industry.

Application Field

The primary application fields for the T1235T-8T are power supplies, lighting and control systems. It is frequently employed with high-power relays or switches in these applications. It can also be utilized in motor controls, power conditioning, and other motor-related applications. This makes the T1235T-8T is an ideal choice for commercial and industrial applications.

The T1235T-8T is also an appropriate device for use in residential insulation applications. Its low junction capacitance and low turn-on/off static power drain make it well suited for these types of applications. Its low voltage drop across the load makes it ideal for controlling both AC and DC loads.

Working Principle

The Thyristor works by allowing current to flow through its controlled terminals only when its defined turn-on voltage is reached by the external control circuit. When this occurs, the Thyristor is said to be in a conducting state, allowing current through the device. The T1235T-8T in particular has a breakover voltage of 8 volts, and a maximum current capacity of 12 Amps.

The Thyristor has two general modes of operation. The first is a ‘static’ mode, which is where the device is normally off, and is turned on when the external control current reaches the defined turn-on voltage. The second is a ‘dynamic’ mode, which is where the device is normally on, and is turned off when the current is reduced below the turn-off voltage.

The T1235T-8T has a fast switching action with a control current, which makes it ideal for applications such as stroboscopic light dimming and other rapid current control operations. It also has a low leakage current, and is not affected by contact bounce, which would otherwise cause undesirable cyclic on/off overshoots or noise signals.

Conclusion

The T1235T-8T is a thyristor device, typically employed in the lighting and power industry for power supply, lighting, and control systems applications. Its low junction capacitance, low turn-on/off static power drain, and low voltage drop across the load make it an ideal choice for residential insulation applications, and its fast switching action with a control current make it useful for applications such as stroboscopic light dimming and other rapid current control operations.
