TVS-Diodes are used to protect electronic components from electrical overstress conditions. This includes power surges, voltage spikes, and electrostatic discharges (ESD). The MXP5KE90A TVS-Diode is especially designed to protect low impedance and high capacitance circuits which typical occur in advanced systems.

The MXP series includes a bidirectional diode with symbol as shown:

MXP5KE90A Application Field and Working Principle

The MXP5KE90A is commonly used in portable consumer electronics, including mobile phones, laptops, digital cameras, and gaming consoles. It also finds application in automotive electronics, such as airbags, cameras, and infotainment systems. The specific application for this part is for overvoltage protection with very high levels of surge protection. It is ideal for high frequency, high capacitance and low impedance sources and loads.

The MXP5KE90A employs a unique technology to provide unidirectional protection from surges, spikes and ESD. It has an on-resistance of typically 1.5 ohms with a low capacitance of typically 350pF. When an over stress events occurs, the protection device will conduct current away from the circuits in order to protect them from damage. The transient voltage will be clamped to a voltage of 40V for a single line protection while reverse leakage current is very close to zero.

The MXP5KE90A is designed with a “fail safe” architecture which ensures consistent robust performance and a lifetime of reliability. This device offers the highest tolerance from ESD events, with its on-resistance at maximum remaining at just 1.5 ohms. In addition, it also contains built-in electrostatic discharge protection diodes that offer protection up to 4000 volts.

The MXP5KE90A is suitable for use in dense PCB applications due to its small size and robust design. It also offers excellent thermal performance, with a thermal derating factor of 2%. It is available in 5 pin TSSOP and 3 pin SMI packages.

The MXP5KE90A is a versatile device, suitable for a wide variety of applications. It is a reliable and cost effective solution for the protection of high capacitance and low impedance sources and loads. As well as this, it provides excellent thermal performance, robustness and reliability. It is ideal for use in consumer electronics and automotive applications.
