2EZ47D5E3/TR12 application field and working principle

A 2EZ47D5E3/TR12 diode is a silicon-controlled rectifier (SCR) diode which is used in various applications. It is used as a switch in some power supplies, as a switch in lighting systems, as a motor driver, or as a timing or current control device. It is a low-voltage device that is designed to be used in circuits up to 240 VAC. The 2EZ47D5E3/TR12 is a 4-terminal device, with two anodes, two cathodes, and a control gate.

When current is applied to the anode, a hole-electron pair triggers a process of hole diffusion across the PN junction. This causes avalanche breakdown, where a large current begins to flow. This current is called the “on-state current”. The current remains on until the reverse-biased voltage exceeds the breakdown voltage, which turns off the device. The reverse-biased voltage is called the “off-state voltage”. The voltage corresponding to off-state voltage is called the “enable voltage”.

The 2EZ47D5E3/TR12 is a current-controlled device. An external voltage applied to the control gate controls the current conduction. The control gate is a third electrode between the anode and the cathode. This third electrode is used to control the conduction path between the anode and the cathode. The voltage applied to the control gate must exceed the threshold voltage, which is the voltage required to turn the SCR on. The current flowing through the device is proportional to the voltage applied to the control gate. This makes the device highly sensitive to tiny changes in the control gate voltage.

The 2EZ47D5E3/TR12 is a versatile device with a variety of applications. It can be used as a switch in various power supplies such as computer power supplies, UPSs, and motor controllers. It can be used as a switch in lighting circuits or motor drivers. It can also be used as a timing or current control device for controlling the speed of motors, or controlling switching on voltage waves.
