MXL5KP78A is a flat mounted, low capacitance, high-performance Transient Voltage Suppressor (TVS) Diode. It is generally used in equipment with power or signal lines for over-voltage protection. This type of device is essential for product design to reduce losses caused by transient surges and electrostatic discharges.

MXL5KP78A is designed to protect electronic devices from sudden power surge caused by load switching, short circuits, lightning, heavy inductive loads, and electrostatic discharges. It is available in a 5.0x6.1mm SMD package with an ultra low 5pF capacitance. It has over temperature and over voltage protection, with a holding voltage of 85 V. The device also has a reverse leakage current of 10mA and a maximum peak pulse power rating of 150 W.

For applications which require protection of sensitive electronic components, the MXL5KP78A is a reliable solution. Its low capacitance and fast switching speed make them an ideal choice for protection of sensitive ICs and connectors. Its high peak pulse power rating makes it suitable for a wide range of applications, including industrial and automotive.

MXL5KP78A provides overvoltage protection at 85V, with its overvoltage protection circuit triggered by any voltage above this level. When the voltage exceeds this level, the device goes into a low impedance state, and the overvoltage current is diverted away from the protected circuit. The device then quickly returns to its high impedance state once the voltage returns to the normal operational level.

The MXL5KP78A is also designed to protect against over-temperature conditions. The device has a thermal shutdown voltage of 125°C, which is triggered by any internal temperature exceeding this level. The device then enters a low impedance state until the temperature drops back to the normal operational level.

In addition, the MXL5KP78A provides electrostatic discharge protection up to a maximum working voltage of 8kV. The device is designed to absorb any surge of static electricity that falls within the allowable operating voltage range. This protection is provided when the voltage between the device and ground rises above its threshold voltage. The device then quickly switches from a high impedance state to a low impedance state and dissipates the static electricity.

The MXL5KP78A is a versatile and reliable solution for protecting sensitive electronic components from overvoltage, over temperature, and electrostatic discharge. Its low capacitance, fast response time and high peak pulse power rating make it an excellent choice for applications where protection from transient surges and electrostatic discharges is required.
