T607081884BT

Introduction

T607081884BT is a two-quadrant three-terminal Thyristor (TQTT), among the widest used types of SCR (silicon-controlled rectifier). The two-quadrant thyristor is designed for operation in two conducting directions meaning it can conduct in either direction when the gate receives a positive or negative trigger. The T607081884BT SCR is symmetric and is suggested as an economical solution for half-wave rectifiers, extended on-off control, static switching, phase control, temperature control, and phase angle firing of thyristor controlled power factor regulators and charging devices.

Application Field

By using this type of thyristor, there are many application fields and areas in which it can be useful. Here are some of the most common areas in which T607081884BT can be effective:

• Low power control of AC equipment.
• Universal motor control, using U motor startup triggering.
• Power factor correction of single and three-phase circuits.
• Static switches for motor speed control or other AC power applications.
• Voltage regulation, static harmonic improvement.
• Overcurrent protection, current limiting, current smoothing.

Working Principle

The working principle of the T607081884BT two-quadrant thyristor is simple. When the SCR is unbiased, meaning that the gate and anode connection is open and no current travels along the SCR, the SCR stays in its off state. This is the average state of the SCR and is known as a blocking state. When a positive or negative pulse is applied to the gate terminal, the thyristor is forced into the on state, allowing current to travel from anode to cathode. As such, a thyristor acts as an electric switch. The device can then remain conducting until the current drops below a minimum value known as the holding current. When the current drops below the holding current, the device will turn off and again enter its blocking state.

Conclusion

To conclude, this article has offered an overview of the T607081884BT two-quadrant thyristor and its application fields. The device is a widely used type of silicon-controlled rectifier which can be used in a variety of applications. The working principle of the thyristor is fairly simple and can be understood by anyone with a basic understanding of electricity. Therefore, the T607081884BT can be recommended as an economic solution to many electric and power control applications.
