TVS (Transient Voltage Suppressor) diodes are designed to protect electrical appliances from overvoltage transients due to electrical spikes and surges. The MPLAD15KP200AE3 is a unidirectional low capacitance diode designed to provide fast response time and superior clamping performance. It is also designed to protect up to 15 kilovolts of peak pulse power.

In applications where power line transients could cause permanent damage to sensitive circuits, the MPLAD15KP200AE3 provides protection and increases system reliability. The MPLAD15KP200AE3 is designed to provide maximum protection against electrical transients, UVLO (under-voltage lockout), ESD (electrostatic discharge) and EFT (electrical fast transient) events. It is also designed to dampen voltage spikes, ripple current, and surge voltage.

The MPLAD15KP200AE3 features a 1.2 pF lead capacitance which provides low capacitance and fast response time. It also features a 1500 W peak pulse power handling rating, a breakdown voltage range of 14.1 V to 15.2 V, and a Stand-off voltage of 12 V. The maximum leakage current is 50 uA.

The MPLAD15KP200AE3’s working principle is based on avalanche breakdown. An avalanche diode is a voltage-dependent diode which has a relatively large reverse breakdown voltage in comparison to other diodes. In an avalanche breakdown, a large voltage applied to the diode causes a high electric field which causes electrons to be accelerated to high energies and generate additional electron-hole pairs throughout the entire lattice structure of the material. This in turn creates a large avalanche current which increases exponentially with the applied voltage.

When an overvoltage transient occurs, the MPLAD15KP200AE3 provides protection by diverting the energy surge away from sensitive components and clamping the voltage within a safe level. It does this by utilizing the avalanche breakdown and consuming the energy of the surge. The MPLAD15KP200AE3 is designed to limit the voltage to a safe level by converting the energy from the surge into heat and dissipating it in an externally mounted heat sink.

The MPLAD15KP200AE3 is designed to provide protection for electrical systems in a broad range of applications, including automotive and power supply protection. With its low capacitance and fast response time it is ideal for protecting sensitive electronic circuits from ESD, EMI, and other transient events.

In summary, the MPLAD15KP200AE3 is a unidirectional low capacitance diode designed to provide protection from overvoltage transients. Its low capacitance and fast response time makes it ideal for protecting sensitive electronic circuits from ESD, EMI, and other transient events. The MPLAD15KP200AE3 utilizes the avalanche breakdown principle which diverts the energy surge away from sensitive components and clamps the voltage within a safe level. It is suitable for a wide range of applications, from automotive and power supply protection to providing protection for sensitive electronic circuits.
