VHF85-14IO7 Discrete Semiconductor Products

Thyristors - SCRs - Modules

VHF85-14IO7 is a series of thyristors developed by Infineon. It is a so-called series connection module, also known as a semiconductor switch, which is composed of semi-conductive gate, anti-parallel diode and triode. The main purpose of it is to control the circuit. Because of its wide operating temperature range, fast reaction speed and long-term stability, it has been widely used in electric industry. Furthermore, it has higher current capacity than other thyristors.

Application Field

VHF85-14IO7 has a wide application in the fields of power equipment, electric vehicle charging and frequent power switch. It can be used as electromagnetic relay and solid state relay. It can provide motor speed control, motor drive and soft start/stop circuit for home appliances. In addition, it can also be used for melting and welding application in electrical equipment.

Working Principle

The working principle of VHF85-14IO7 is based on the properties of thyristors. When the trigger voltage is applied at the gate electrode of the thyristor, it allows the current to start flowing through the electrodes causing a potential difference. This potential difference causes the thyristor to switch on and stay on until the current is removed. Different thyristors have different voltage and current ratings which is specified in its datasheet. The range of voltage and current can be selected according to the specific application requirements.

We should pay attention to the fact that VHF85-14IO7 should be regularly monitored to confirm their normal working state. When it is found that its output current is not within the range of its rated continuous current, it should be further investigated to identify the cause and the underlying problem should be corrected to prevent possible damages or accidents.

Conclusion

VHF85-14IO7 has wide application fields in the power industry. Its main purpose is to control the circuit. It works on the principle of thyristors which allows the current to flow when its gate is triggered. It has high current capacity which makes it suitable for high-power applications. It is important to regularly monitor its working state to ensure its safety and normal operation.
