Thyristors - SCRs

A thyristor is a solid-state semiconductor device with three or more terminals. It is a four-layered, three-junction semiconductor device, having the following properties: an anode, a gate, and a cathode. A SCR, or silicon controlled rectifier, is a type of thyristor most commonly used in high power applications. The SCR that is most widely used is the T607101854BT.

Application Field and Working Principle of the T607101854BT

The T607101854BT SCR is ideally suited for applications requiring high current and high voltage operations. Applications include AC motor controllers, battery chargers, DC motor controllers, inverters, power supplies, rectifiers, and welders. The device is designed for multiple turns on and off operations in the medium frequency range and is highly resistant to noise.

The working principle of the T607101854BT is based on the forward voltage applied at its anode terminal (positive) with respect to its gate terminal (negative). If a forward voltage is applied to the anode with respect to the cathode and a positive trigger voltage is applied to the gate terminal, the device is triggered. This results in the flow of current through the main terminals. When the trigger voltage is removed, the device is turned off and the current flow between the main terminals is stopped.

The unique features of the T607101854BT make it well suited for applications requiring long life and high reliability. It has a surcharge dead time of 140 microseconds, a holding time of 120 microseconds and a continuous current capability of 800mA at 120V with a surge rating of 25A. The device also has a low leakage current of just 50 µA.

The T607101854BT is designed for use in applications where load current is a significant part of the system design. The device is ideal for use in switched mode power supplies, motor controllers, and rectifiers. It is also a good choice for applications requiring fast switching speeds, low power losses, and a low voltage drop across the device.

The T607101854BT offers a wide range of features which make it a great choice for applications requiring high current and high voltage operations. It is a reliable and cost effective solution for any application requiring a medium frequency switch.
