Thyristors – SCRs

Thyristors, or silicon controlled rectifiers (SCRs), are three terminal devices that effectively form a switch, acting as a rectifier in the off state, and as a switch with controlled conduction characteristics in the on-state. SCRs are available in a variety of physical packages to suit your application needs.

The T607081534BT is a 4A, 800V three-phase bridge rectifier thyristor module. The T607081534BT has an insulated metal case, providing protection against short circuits, reverse polarity, stray fields, and UV radiation. The case is made of highly conductive aluminum material for ultimate protection and mechanical strength.

The working principle of the T607081534BT is based on the PNPN structure of a thyristor, where the negative gate current turns the thyristor on as a switch, and then turns off when the negative gate current is removed. The on-state resistance of the T607081534BT varies from 0.2 ohms to 0.4 ohms, making it ideal for applications requiring high power and low voltage drop.

The main application areas of the T607081534BT are in power supplies, motor drives, and AC regulators. The T607081534BT can be used in rectifying and switching applications such as controlling switches and relays, controlling resistive and inductive loads, filtering electrical noise, and controlling high voltage and current transients. Additionally, the T607081534BT can be used in the most common adjustable DC power supplies and controllers, including the Kontrolknop DC power supplies.

In power supplies and motor drives, the T607081534BT provides full bridge rectification, allowing the elimination of electrolytic capacitors while providing almost perfect power supply regulation. In AC regulators, it can be used as a controllable switch, allowing high frequency control of AC voltage, current, and power up to and including 800V, 4A.

In addition to its main applications in power supplies, motor drives, and AC regulators, the T607081534BT can also be used for efficient electrical noise filtering, controlling switched and relays, controlling high voltage and current transients, and boosting low voltage from power sources. Furthermore, its ability to control high current transients is particularly beneficial for applications requiring substantial power dissipation such as medium voltage, high current mains.

In conclusion, the T607081534BT bridge rectifier thyristor module is a versatile and effective device that can be utilized in a variety of applications. The T607081534BT is a highly reliable device with an insulated metal case, providing protection against short circuits and reverse polarity, offering both high efficiency and protection of the device. The working principle of the T607081534BT is based on the PNPN structure of the thyristor device, while its main application areas are in power supplies, motor drives and AC regulators.
