A Transient Voltage Suppressor (TVS) diode is the most commonly used component when it comes to protecting electronic products. The MQ1N8165 is a TVS diode designed to protect electronic circuits from over voltage transients. It has a very low clamping voltage which enables it to absorb high voltage spikes, preventing them from damaging sensitive circuitry.

The main application of the MQ1N8165 is surge protection in automotive electronic systems. It is typically used to protect sensitive electrical components from voltage spikes that can occur in the event of a short circuit, over voltage, and reverse voltage conditions. The MQ1N8165 is designed to provide maximum protection from voltage transients while maintaining a low static and dynamic capacitance to ensure signal integrity.

The working principle of the MQ1N8165 TVS diode is based on a semiconductor N-type structure. The TVS diode is a unidirectional device that allows current to flow through it in only one direction. In normal operation, the diode will pass current just like any other diode. However, when the voltage across the diode exceeds its maximum reverse voltage rating, the diode becomes reverse biased and the current is blocked. At this point the MQ1N8165 enters its breakdown region and begins claming the voltage. This provides a protective shunt for the sensitive circuitry, dissipating the excess voltage as heat.

The MQ1N8165 is a low capacitance diode designed for high-speed data line protection. It features a low operating voltage of 5.0V and a very low clamping voltage of 9.3V. Its high surge capability and low capacitance makes it ideal for high-speed data line applications such as USB, HDMI, and Ethernet. It has a very fast response time and is able to absorb high voltage transients quickly and efficiently.

The MQ1N8165 is a unique TVS diode that offers superior performance when it comes to protecting your electronic circuits from over voltage transients. It features a low operating voltage, a low clamping voltage, and a fast response time. Its high surge capability and low capacitance makes it an ideal choice for high-speed data line protection.
