Q2016LH4 Application Field and Working Principle

Thyristors are solid-state semiconductor devices that offer high voltage and amperage control. Used in power electronics and industry, thyristors can vary the amount of AC current that goes through the device by sensing the amount of current that is drawn by the load and accordingly activating and deactivating the device. The Q2016LH4 is a highly efficient and robust thyristor device that can be used in a variety of applications.

What Is the Q2016LH4?

The Q2016LH4 is a four-lead thyristor device from the semiconductor chip manufacturer ON Semiconductor. It is a robust and highly efficient device designed for a variety of industrial applications, including pulse width modulation, AC voltage and current control, DC to AC conversion, and dimming and brightness control. The device is rated for a reverse voltage rating of 600V, an on-state current of 16A, a triggering current of 2.5A, and has a maximum surge current of 120A.

What Is the Working Principle of the Q2016LH4?

The thyristor is a three-terminal semiconductor device, made up of a gate, an anode, and a cathode. When a current is passed through the gate of a thyristor, its resistance drops, allowing current to flow through the other two terminals. When the current through the gate is reversed, the device switches to its off state, blocking current flow.The Q2016LH4 is a 4-pin thyristor device, making use of four terminals instead of three. These are the gate, anode, cathode and gate-buffer (commonly referred to as the “7th pin”). The gate buffer is used to regulate the current going into the gate, thus reducing the need for an external gate-driving circuit.

What Are the Application Fields for the Q2016LH4?

The Q2016LH4 is a robust and highly efficient thyristor, making it well suited for a variety of industrial and power-electronics applications. It can be used for AC voltage and current control, such as in dimmers, power supplies, motor drives, and AC to DC converters, as well as pulse width modulation. Additionally, by controlling the gate voltage, the Q2016LH4 can be used to enhance the performance of other power electronics components, such as SCRs, TRIACs, and IGBTs.

Conclusion

Thyristors are an important component in power electronics. The Q2016LH4 is a robust and highly efficient thyristor device, making it suitable for a wide range of industrial applications. Its four-pin design reduces the need for external gate-driving circuits, allowing for more efficient and precise control over voltage and current flow. The Q2016LH4 is a popular choice for applications such as SCR, TRIAC, and IGBT enhancement, pulse width modulation, AC voltage and current control, and DC to AC conversion.
