Thyristors - SCRs (Silicon Controlled Rectifiers) are electronic components that, like transistor, act as switches. They can be used to control large amounts of current and voltage. Among several available types and models, T72H084854DN stands out as a semiconductor switch with a range of applications and special specifications.

Applications

The device T72H084854DN is primarily used for AC switching applications and can handle current of 16A and voltage of 600V. It can be used for switching applications such as motor control, AC power control, lamp control and voltage regulation. It is also used in an array of other high power applications such as welding, automation and machine control for the purpose of controlling currents and voltages.

Design

The T72H084854DN is designed with a planar construction where the metal oxide silicon (MOS) gates are connected directly to the metal and metal oxide layers. This structure makes the device have a high voltage isolation capability. It also features metal oxide field plates that enable higher latching current to be controlled as well as allowing over-voltage protection. In addition the device features integral gate-emitter resistors with reduced saturation voltages that reduce losses.

Working Principle

The T72H084854DN works in three stages: the gate turn-on, the gate turn-off and the latch-up. During the gate turn-on stage, a voltage is applied to the gate terminal of the device. This voltage triggers the device which causes the current through it to be increased. During the gate turn-off stage, the current through the device is reduced by either removing the source current or a negative voltage being applied to the gate terminal. In the latch-up stage, the device is in its quiescent state and the current through the device is constant.

Conclusion

The T72H084854DN is a thyristor (SCR) device designed for use in AC switching applications. It is designed to handle a current of 16A and a voltage of 600V. It has a range of applications that include motor control, lamp control, voltage regulation and several other high power applications. The device works in three stages, namely, the gate turn-on, the gate turn-off and latch-up.
