A5030UC6LRP

TVS – Thyristors

A5030UC6LRP thyristor is a three-terminal semiconductor device with four layers of alternating P and N-type materials which is used for switching and protecting loads against high or low voltage. When an a.c or d.c voltage is applied to the gate terminal of a thyristor, it first gets forward biased. This allows a small amount of current to flow through the gate leading to the triggering of the thyristor. When the thyristor is triggered it becomes conducting and allows the current to flow through the device.

The A5030UC6LRP application field includes a.c and d.c motor control, load control, phase control, and solenoid control. The device is used in industrial applications to control high voltage and/or current. It is also used in power switches and in other electronic equipment such as power supplies, UPS systems, automotive electronics and UPS systems.

Working Principle of A5030UC6LRP

The working principle of A5030UC6LRP thyristor is based on the behaviour of four layers of alternating P-type and N-type materials. When the gate is forward biased it allows a small amount of current to flow through it. This current is called gate current. This gate current that flows through the device causes a voltage drop across the base junction of the thyristor. This voltage drop allows for a current to flow through the device. This current is called ‘black current’. The current flowing through the device increases with the increasing gate current and ultimately a current reaches the level to fire the thyristor. This current is called ‘the trigger current’.

When the thyristor is triggered, it becomesconducting and current passes through it. The device continues to be in the conducting state until the current through the device is removed or becomes zero. At this point, the device is cut off and the device reverts to a non-conducting state. The process of ‘triggering’ and ‘cutting off’ the device is repeated every time power is applied.
