MPLAD18KP8.0CAE3 application field and working principle

A TVS (transient voltage suppressor) diode is an electronic component normally used to protect circuits from excessive voltage transients usually caused by electrostatic discharge (ESD) or lightning irregularities. The MPLAD18KP8.0CAE3 is a silicon-avalanche diode TVS specifically designed for ESD and lightning protection applications in consumer electronics. The device is aimed primarily at ESD protection, with advanced features such as low operating voltage and low leakage current.

The MPLAD18KP8.0CAE3 offers very fast switching speeds (low 5 pJ typical ESD protection) and excellent suppression performance to meet the requirements of IEC 61000-4-2.The device is a bidirectional transistor with an integrated ESD protection diode network for symmetrical protection. The integrated TVS diode network offers superior clamping capability to safely dissipate overvoltage transients.

The MPLAD18KP8.0CAE3 offers superior protection against excessive operating voltages and current transients, with a maximum peak pulse power dissipation of 625W. It is designed with a leakage current of 5A typical and a maximum operate voltage of 18V. Due to its low leakage current, the device can be easily connected directly to an upstream port or internal power supply.

The TVS diode is the most versatile and reliable way to protect a circuit from overvoltages. It is a solid-state device designed to absorb the energy of electrical transients, or spikes, before they can damage the components of the circuit. The MPLAD18KP8.0CAE3 provides fast protection against the most common causes of electrical transients, such as lightning, ESD, etc. The device is also designed to handle transients up to 18V, so it can effectively absorb and dissipate higher energy spikes.

The working principle of the MPLAD18KP8.0CAE3 is that the diode has a special capacitor-like structure. When a voltage transient strikes, the junction of the diode charges up the capacitor, dissipating the voltage and clamping it down to a safe level. This helps to protect the sensitive components in the circuit from being damaged due to the transient. When the voltage reaches a threshold level, the diode switches off, so the protection is only active during actual transients.

The MPLAD18KP8.0CAE3 is well suited for a variety of applications, including Audio and Video Protections, USB Protections, Automotive Protections, and PoE (Power-over-Ethernet) Protections applications. The device provides fast clamping performance, low operating voltage, and very low leakage current, making it the perfect choice for ESD and lightning protection applications.
