TVS - Diodes are an important type of semi-conductor component device, used for protection against over-voltage and electrostatic discharge (ESD). The MXL5KP16AE3 is a uni-directional device with an operating voltage of 16V that is specifically designed for applications requiring high levels of Data Line Overvoltage protection and ESD protection.

MXL5KP16AE3 Application Field

The MXL5KP16AE3 is a low-capacitance device, with low clamping voltages that can be used to protect the circuits from ESD and Delta EMI. This includes a wide range of electrical and electronic applications; from consumer appliances and automotive electronics, to PC motherboards and communication equipment.

The device is capable of protecting 1-line and 4-line data lines, including USB and HDMI transceivers, DisplayPort ports, Gigabit Ethernet and Serial ATA (SATA) ports. It can also protect RF communication ports and audio jacks, as well as automotive electronics such as CAN, LIN, and Flexray. The MXL5KP16AE3 device can also be used to provide protection from surge transients, usually of the order of 1.2/50µs, as well as protection from electrostatic discharges in the range of +/-8kV contact, +/-15kV air.

MXL5KP16AE3 Working Principle

The device is a single line, unidirectional Electrostatic Discharge (ESD) and Overvoltage Transient Suppression Diode (TVS), with a uni-directional breakdown voltage of 16V and a Rise Time of only 0.25 nanoseconds.

When the voltage at the device\'s anode exceeds the specified breakdown voltage of 16V, the device enters a conductive state, allowing a high amount of current to flow through until the peak transient voltage is reduced to a safe level. During this time, the current through the device is limited to whatever load is present on the line. This is done to provide protection against both over-voltage and device damage.

Once the voltage is reduced below the safe limit, the device will return to its non-conductive state, blocking any further current flow and returning the device to its original state. This process of providing a safe limit for current flow helps to prevent excessive current draw, device damage, and data loss in many applications.

The MXL5KP16AE3 can also be used in reverse voltage protection applications, where it is used to protect sensitive components from voltage spikes caused by a reversed polarity. This device can also be used in over-voltage protection applications, where it is used to limit the amount of current flow through a circuit, and to protect the load from potentially damaging over-voltage transients.

Conclusion

The MXL5KP16AE3 device is a versatile, low-capacitance unidirectional transient voltage suppressor diode, which provides reliable, low voltages, high speed protection of data lines against ESD, Delta EMI, and surge transients. When used as prescribed, it can protect a wide range of different electrical and electronic applications from potential damage due to overvoltages and electrostatic discharges.
