TVS Diodes are devices used mainly to provide a level of protection against electrical transients such as lightning and electrostatic discharge (ESD). The MX1N8178 is a leaded Zener diode TVS with an array of features.

Application Field and Performance Characteristics

The MX1N8178 has a wide range of applications in automotive, medical, industrial, consumer and audio video systems. This diode can handle transients with a peak working voltage of 1.5 volts and a peak pulse current of 55.7 Amperes. It also has a low clamping voltage of 1.2 volts, which ensures protection for more sensitive electronics. Moreover, its low capacitance offers the best immunity to high frequency interference. The diode has an operating temperature range of –55°C to 125°C, making it suitable for applications in extreme conditions.

Working Principle

The MX1N8178 Zener diode TVS works on the principle of the Zener voltage breakdown effect. When an excessive voltage is applied to the diode, it allows the current to travel through it. If the voltage is higher than the Zener voltage, the excess voltage passes through the diode and is dispersed across the residual components of the circuit. This prevents damage to any component and safeguards the device against transients.

Design Features

The MX1N8178 has a diameter of 1 mm, making it an ideal choice for controlling EMI and ESD in space-constrained applications.
