TVS - Diodes: MV1N8162US application field and working principle

TVS-Diodes (Transient Voltage Suppressor Diodes) are electro-optic components that protect against voltage transients and overvoltages in electronic circuits. They are specifically designed for fast response times and are used to safeguard circuits from dangerous voltages spikes and transient situations. This article will provide an overview of the application fields and working principle of MV1N8162US, an automotive-grade surge protection diode from Littelfuse.

Application of MV1N8162US

MV1N8162US, from Littelfuse’s AEC-Q101 qualified TVS diode series, is specifically designed to protect automotive circuits from voltage transients, electrostatic discharges, and power supply voltages spikes. These automotive-grade diodes are appropriate for use in circuit boards and can be easily mounted on them. The diode is also used as an alternative for mechanical fuses and is ideal for applications with a transient environment, such as in automotive, industrial, and telecom applications. Moreover, MV1N8162US diodes have the capability to protect the circuit and equipment against over-voltage discharges such as lightning strikes, short circuits, and inadvertently connecting power cables in reverse polarity. The diode is a snap-off type that ensures easy and quick installation and can be snapped off easily when it is necessary to remove the device. The diode is available in packages such as 6-pin DIP, SOT-23, SOP-8, and SMD Dual Chip devices.

Working Principle of MV1N8162US

The MV1N8162US diode is a two terminal electronic component which is made up of a junction between two different types of semiconductor material. The two-terminal component enables the diode to protect the circuit from high-voltage transients. During normal operation, the diode acts as a closed switch and allows current to flow through it. However, when the voltage exceeds the breakdown voltage of the diode, the diode immediately switches to an open state and prevents the current from passing. This allows the diode to protect the circuit against high voltage transients.The breakdown voltage of the diode is determined by a number of factors, including the manufacturing process, temperature, and junction architecture. The higher the breakdown voltage of the diode, the greater the immunity to voltage transients. This is why it is important to select the right TVS diode for an application with the required breakdown voltage. Additionally, the diode needs to be rated for a power rating that is at least equal to the power expected to be dissipated in the circuit.

Conclusion

MV1N8162US, from Littelfuse’s series of AEC-Q101 qualified TVS diodes, is used to protect automotive circuits from voltage transients, electrostatic discharges, and power supply voltages spikes. It is suitable for applications in automotive, industrial, and telecom environments. The diode works by breaking down at the set breakdown voltage when the voltage exceeds this value and provides protection for the circuits. The breakdown voltage of the diode should be selected according to the power rating of the expected load.
