MQ1N8182US Circuit Protection

TVS (Transient Voltage Suppressors) diodes provide protection against transient voltage surges in the form of Lightning, Electrostatic Discharge (ESD), inductive load switching, and other electromagnetic pulses or interference. The MQ1N8182US (Low Capacitance Unidirectional ESD Protection Diode) is an example of such a device. It is designed for use as a cable protection diodes in high-speed data-line applications, including Universal Serial Bus (USB) protection, Ethernet protection, and similar systems.

The MQ1N8182US device utilizes a high voltage Vertical Diffused MOS (VDMOS) technology structure. This enables axial leads and provides a low capacitance of 5pF typical at 1KV rated ESD working voltage. It delivers superior ESD protection in unidirectional applications where the ESD voltage is below the rated voltage. The device’s built-in ESD diode protection provides an effective protection and ensures reliable service.

The MQ1N8182US device is composed of 3 terminals, consisting of two main terminals and one support terminal. The two main terminals are mounted through the support terminal, which helps to provide a steady connection and to hold them in place. The two main terminals act to channel the voltage into the device and protect it from excessive voltage. The support terminal is used to provide power and ground connection to the device.

The MQ1N8182US can provide ESD protection up to 8KV (Class III) and offers low-capacitance for high-frequency analog/ digital applications. It should be connected between the signal line and ground, and its common mode transient voltage protection operates in the opposite direction to the signal line (i.e., it must be connected to the side of the signal line that is closer to the ground for higher levels of protection).

The MQ1N8182US is suitable for a wide range of applications, where it can provide low-capacitance ESD protection for high-speed data lines. These include USB, HDMI, Ethernet and other similar systems. Additionally, the device is suitable for communication systems with high-resolution video. The use of the MQ1N8182US can significantly reduce the risk of data corruption or loss due to ESD or other transient voltage surges.

The MQ1N8182US can be used to protect a wide range of signal lines from unscheduled outages, surges, and damages. By combining the built-in VDMOS devices, and its low capacitance design, it enables reliable signal transmission over the protected lines. The device is designed to be inserted into a circuit prior to the protected circuitry, and its clamping action helps to protect the circuit from any overvoltage that may be present.

In summary, the MQ1N8182US (Low Capacitance Unidirectional ESD Protection Diode) is a device designed to provide transient voltage surge protection in high-speed data-line applications. Due to its high voltage VDMOS technology, it has a low capacitance of 5pF typical at 1KV rated ESD working voltage and offers reliable protection with no risk of data corruption or loss due to ESD or other transient voltage surges. As such, it represents an ideal solution for a wide range of communication systems and can help to protect a variety of signal lines from both unscheduled outages and surges.
