SEMIKRON spare parts SKKT 570/16E

The method of identifying the three poles of a thyristor is very simple. According to the principle of P-N junction, simply measure the resistance value between the three poles with a multimeter.

The forward and reverse resistance between the anode and cathode is several hundred kiloohms or more, and the forward and reverse resistance between the anode and the control electrode is several hundred kiloohms or more (there are two P-N junctions between them, and the directions are opposite, so the anode and control electrode are not connected in both directions).

There is a P-N junction between the control electrode and the cathode, so its forward resistance is approximately in the range of a few ohms to several hundred ohms, and the reverse resistance is larger than the forward resistance. However, the characteristics of the control diode are not ideal. It is not in a blocking state in reverse and can have a relatively large current passing through. Therefore, sometimes the measured reverse resistance of the control diode is relatively small, which does not necessarily indicate poor control diode characteristics. In addition, when measuring the forward and reverse resistance of the control electrode, the multimeter should be placed in the R * 10 or R * 1 position to prevent the reverse breakdown of the control electrode due to high voltage.

If the positive and negative poles of the component are short circuited, or the anode and control pole are short circuited, or the control pole and cathode are short circuited in the opposite direction, or the control pole and cathode are open circuited, it indicates that the component is damaged.

Silicon controlled rectifier (SCR) is a high-power semiconductor device with a four layer structure consisting of three PN junctions. In fact, the function of a thyristor is not only rectification, but it can also be used as a contactless switch to quickly turn on or off circuits, realizing the inversion of direct current into alternating current, converting one frequency of alternating current into another frequency of alternating current, and so on. Like other semiconductor devices, thyristors have advantages such as small size, high efficiency, good stability, and reliable operation. Its emergence has brought semiconductor technology from the weak current field to the strong current field, becoming a component that is eagerly adopted in industries such as industry, agriculture, transportation, military research, as well as commercial and civilian electrical appliances.

1. Noise level on the gate

In an environment with electrical noise, if the noise voltage on the gate exceeds VGT and there is sufficient gate current to excite positive feedback inside the thyristor, it will also be triggered to conduct.

When installing an application, the first step is to make the connection outside the gate as short as possible. When the connection cannot be very short, twisted or shielded wires can be used to reduce the intrusion of interference. Add a 1K Ω resistor between G and MT1 to reduce its sensitivity, or connect a 100nf capacitor in parallel to filter out high-frequency noise.

2. Regarding the conversion voltage change rate

When driving a large inductive load, there is a significant phase shift between the load voltage and current. When the load current crosses zero, the bidirectional thyristor (thyristor) begins to reverse direction, but due to the phase shift, the voltage will not be zero. So it is required that the thyristor (thyristor) quickly turn off this voltage. If the change in commutation voltage exceeds the allowable value at this time, there is not enough time to release the charge between the junctions, and the bidirectional thyristor (thyristor) is forced back to the conducting state.

To overcome the above problems, an RC network can be added between terminals MT1 and MT2 to limit voltage changes and prevent false triggering. Generally, the resistor is set to 100R and the capacitor is set to 100nF. It is worth noting that this resistor cannot be omitted.

3. Regarding the conversion of current change rate

When the load current increases, the power frequency increases, or the power supply is non sinusoidal, the rate of change of the conversion current increases. This situation is most likely to occur under inductive loads and can easily lead to device damage. At this point, a few millihenries air inductor can be connected in series in the load circuit.

4. Regarding the open circuit voltage change rate of thyristors (thyristors) DVD/DT

When a rapidly changing voltage smaller than its VDFM is applied across the two ends of a bidirectional thyristor (thyristor) in the cutoff state, the current of the internal capacitor will generate sufficient gate current to make the thyristor (thyristor) conductive. This is particularly severe at high temperatures, in which case an RC buffer circuit can be added between MT1 and MT2 to limit VD/DT, or high-speed thyristors (thyristors) can be used.

5. Regarding the Continuous Peak Open Circuit Voltage VDRM

In the case of abnormal power supply, the voltage across the thyristor (thyristor) will exceed the maximum value of the continuous peak open circuit voltage VDRM, and the leakage current of the thyristor (thyristor) will increase and break down for conduction. If the load can allow a large surge current, then the local current density on the silicon wafer will be very high, causing this small portion of the lead to pass through. Causing chip burning or damage. In addition, incandescent lamps, capacitive loads, or short-circuit protection circuits can generate high surge currents. In this case, filters and clamp circuits can be added to prevent spike (burr) voltages from being applied to the bidirectional thyristor (thyristor).

The method of identifying the three poles of a thyristor is very simple. According to the principle of P-N junction, simply measure the resistance value between the three poles with a multimeter.

The forward and reverse resistance between the anode and cathode is several hundred kiloohms or more, and the forward and reverse resistance between the anode and the control electrode is several hundred kiloohms or more (there are two P-N junctions between them, and the directions are opposite, so the anode and control electrode are not connected in both directions).
