TVS (Transient Voltage Suppressors) diodes are used for transient voltage protection of electronic systems. They are commonly found in automotive, aerospace, audio, and video applications. The MXPLAD15KP7.5A is a relatively new TVS diode designed to protect systems from transient voltage events. This article will discuss the application field and working principle of MXPLAD15KP7.5A.

Application Field

The MXPLAD15KP7.5A is designed to protect system components from voltage transients and surges. This diode is usually used in automotive and industrial applications where transient voltage protection is needed. The diode is able to limit voltage overshoots and shorts, thereby preventing system damage. The high-performance and low-profile design makes it a suitable choice for use in small-sized devices and compact applications.

The MXPLAD15KP7.5A is especially suitable for automotive applications due to its high ESD protection. The diode is able to withstand up to 15 kV of electrostatic discharge (ESD) without any permanent damage. This makes it a suitable choice for applications such as automotive sensors, displays, and control systems.

Working Principle

The MXPLAD15KP7.5A operates on the principle of avalanche breakdown. This involves the junction of the diode’s pn layers being exposed to a voltage in excess of the breakdown voltage. This causes the flowing current to reach a high value, resulting in the avalanche breakdown of the junction. The diode then begins to limit the voltage across it to the breakdown voltage.

At the same time, the diode provides protection against ESD events. It uses an integrated circuit design to prevent ESD pulses from travelling along the signal lines. This ensures that the system remains protected even during high-voltage ESD events. The diode also uses Schottky diodes and MOSFETs to provide additional protection from ESD and overvoltage pulses.

The MXPLAD15KP7.5A also features a built-in reverse-blocking mechanism. This is a protective mechanism that prevents current from flowing in the reverse direction, which can damage system components. The protection circuit ensures that current cannot flow in the opposite direction and can protect against surge voltages up to 15 kV.

The MXPLAD15KP7.5A is also suitable for power distribution applications. It is designed for use in both linear and switched mode power supplies, and can be used to protect systems against overvoltage and transients. The diode also features a soft start and shutdown protection mechanism to ensure systems are not damaged during startup or shutdown.

In summary, the MXPLAD15KP7.5A is a high-performance TVS diode designed for use in automotive and industrial applications. It is able to protect against voltage transients and ESD events, and is suitable for use in small-size and compact devices. It also features integrated circuitry which provides additional protection from overvoltage and ESD pulses, as well as reverse-blocking protection.
