Transistors - IGBTs - Modules

APTGT150SK120D1G is a high-resistance and high-current gate-protected thyristor module that helps making connection between gate, anode, and cathode.

This module is widely used in different applications, such as low voltage control, inverters, welding machine, uninterruptible power supply (UPS), solar inverter etc. It provides better protection of static and dynamic components, such as thyristors, rectifying diodes, etc.

Application field

APTGT150SK120D1G is widely used in the voltage regulators and inverters of DC power supplies, AC/DC or AC/AC converters, and various other industrial/portable supplies. It can help protect the sensitive components of the circuit, since they can provide better heat resistance, fast charging time and easy installation.

Moreover,it is especially suitable for controlling the AC and DC circuits, due to its excellent thermal stability and low reverse current. Therefore, it can help improve the efficiency of the electrical system and reduce power loss.

Also, it has a good compatibility with other DC or AC components, such as thyristors, rectifying diodes, resistors and capacitors. In addition, it is suitable for applications that require high current, low on-state losses and good protection.

Working principle

APTGT150SK120D1G is a gate-protected thyristor module. Basically, it consists of a thyristor (or silicon-controlled rectifier) and a gate resistor that provide isolation and protection between the gate and the anode, as well as between the gate and the cathode.

The thyristor is responsible for the switching control of the circuit, while the gate resistor allows control over the current. Moreover, the gate resistor helps to protect the sensitive components of the circuit in case of an over-current or short-circuit situation.

When an appropriate current is applied to the gate, the thyristor starts conducting current and the voltage drop is determined by the size of the gate resistor. The current can then be regulated depending on the gate resistance.

The module operates in two states: a forward state when the current is flowing from the anode to the cathode, and a reverse state when the current is blocked. The protection circuit will switch to its reverse state in a situation where the current exceeds the predetermined values.

Conclusion

APTGT150SK120D1G is an ideal module for use in a wide range of applications. It is highly reliable, provides excellent protection of sensitive components, and can regulate current flow. It is also compatible with various DC or AC components, and has good heat resistance.
