TVS - Diodes are transistors that provide over-voltage protection against damaging levels of electrical current. The MX5KP36AE3 is a relatively new model of this type of device designed and manufactured by NXP Semiconductors. It is an unidirectional over-voltage protection device which is suitable for both low- and high-level over-voltage protection.

Application Field

The application field of the MX5KP36AE3 can be categorized into three major application fields: over-voltage protection of power supplies, over-voltage protection of data communication lines, and over-voltage protection of consumer electronics.

In terms of over-voltage protection of power supplies, the MX5KP36AE3 is used primarily in applications such as power supply units, power adapters, chargers, and other equivalent devices. It is ideal for these applications since it has a working voltage range of up to 36V and breakover protection up to 5kV, providing a high level of over-voltage protection.

In terms of over-voltage protection of data communication lines, the MX5KP36AE3 is suitable for use in Ethernet, USB, and other equivalent lines which are sensitive to transient voltages. It can protect these lines from the circulating current which can lead to line damage.

Finally, the MX5KP36AE3 is suitable for use in consumer electronics such as high-definition television (HDTV) and high-definition video (HDV) since it provides excellent over-voltage protection for both input and output signals. It is especially useful in applications where the device is expected to experience sudden over-voltages, such as lightning strikes and electrostatic discharge.

Working Principle

The MX5KP36AE3 is an unidirectional working device, meaning that it only works in one direction. This is because the device consists of two parts: a low-resistance diode and a negative temperature coefficient (NTC) resistor. The diode allows current to flow only in one direction, and the NTC resistor provides additional protection against over-voltage.

When the over-voltage reaches a certain point, the NTC resistor is activated and begins to absorb energy from the over-voltage, which reduces the voltage to a safe level. The absorbed energy is dissipated in the form of heat, which is then passed on to the surroundings.

The MX5KP36AE3 also has an additional level of protection against over-voltages, which is a series of tiny resistors that are connected in parallel to the diode and NTC resistor. The purpose of these resistors is to limit the current that can flow through the device, thus providing further protection against over- voltage.

In summary, the MX5KP36AE3 is a unidirectional over-voltage protection device designed and manufactured by NXP Semiconductors. Its working principle involves the use of a diode and an NTC resistor to provide both low- and high-level over-voltage protection. This device is suitable for use in applications such as power supply units, power adapters, chargers, and consumer electronics.
