Thyristors - SCRs

Thyristor is a semiconductor device which has different types such as, alternating current (AC) Thyristors and direct current (DC) switch thyristors. SCR is a type of AC thyristor, which is also known as silicon controlled rectifier. It is particularly used for controlling high power AC loads with all types of semiconductor based switching solutions. That\'s why, it is widely used for home appliances such as refrigerators, air conditioners and for industrial purposes like controlling motor speeds, etc. The 2N5061RLRA is one of the most popular SCRs which is exclusively designed for power switching applications.

Application Field of 2N5061RLRA

The 2N5061RLRA is an SCR device designed with an in-built ambient temperature and voltage ratings that is suitable for medium power, AC switching applications in the industrial and home appliance sector. It has value rated up to 600 volts and maximum range of 16 amps, which makes it suitable for a broad range of controllable AC switching solutions. It has built in suppressor to avoid surge current of up to 1000 amps when in contact with the AC load. Additionally, the thickness of the silicon controlled rectifier is optimized with model specific parameters as per applications’ requirement, which ensures reliable performance.

Working Principle for 2N5061RLRA

The 2N5061RLRA is an SCR device, which is based on pin configuration that makes the device easy to use in any application. It works on an open loop configuration with anode and cathode pinout, which makes it suitable for medium power and AC switching applications. The working principle consist of three chains of operation, i.e. Off-state, Forward-Blocking-state and On-state. In the OFF state, the SCR is open due to a reverse bias applied to it, whereby current flow between anode and cathode is avoided. In the Forward-Blocking-state, a forward bias must be applied in order to close the SCR. This results in a need for a voltage spike for operation, namely, the "gate" voltage, to turn on the SCR. During the On-State, the current starts to flow from the anode to the cathode, in the same direction with respect to the voltage applied to the SCR.

Once the SCR is turned on, the current continues to pass even when the gate voltage is removed and the device is said to be latched on to the state in which it has already been turned on. The only way to turn off the SCR is to remove the voltage applied across its anode and cathode pins and then it goes off automatically by a reverse current.

Conclusion

The 2N5061RLRA is one of the best SCR devices designed for medium power AC switching applications. Its robustness and reliability makes it suitable for industrial and home appliance applications. Its built in suppressor limits the surge current and offers reliable operation. The working principle consists of three stages including Off-state, forward-blocking-state and On-state, which ensures effective and reliable operations.
