TVS-diodes, which stands for Transient Voltage Suppressor Diodes, are voltage-controlled devices used to reduce overvoltage transients and prevent destruction of other components. They are made from a wide variety of materials and are used for both applications requiring instant response and those using pulse width modulation. The MPLAD18KP85CA is an example of a TVS-diode application.

This device is a low-noise, high-speed, wide temperature range TVS diode with Y5V zinc oxide varistor properties. It is suitable for high-voltage applications ranging from 125V to 1000V. The diode is ideal for use in automotive, industrial, telecommunication, and consumer electronic applications. An integrated dynamic high-frequency filtering circuit provides improved surge protection and high-frequency ESD protection.

MPLAD18KP85CA is suitable for load-dumping protection and overvoltage protection. It is designed with a well-defined collapse and 110nF dissipation capability, providing protection against surges and spikes up to 6KV. The device operates over a wide temperature range (from -55°C to +105°C) and low impedance (<0.3 Ohms at 0V and 200V).

The principle of operation of the MPLAD18KP85CA is quite simple. When an over-voltage is detected, it automatically triggers the device and its integrated switching element to quickly clamp, dissipating energy. This protects other components from harmful voltage spikes. The device also features a well-defined quick-response soft-clamp current, which helps reduce the response time and minimize the effect of the overvoltage.

The MPLAD18KP85CA is ideal for automotive and industrial systems, including power supplies, motor control circuits, servo systems, and turn-on supply circuits. It can also be used in audio circuits to protect against electrical interference, digital circuits to guard against static interference, and telecom circuits.

The MPLAD18KP85CA provides fast response, exceptional surge capability, and low leakage current. It is also able to handle a wide range of operating voltages and temperatures, ensuring reliable protection in a wide variety of applications. The device is RoHS compliant, a necessary requirement for many applications.

Overall, the MPLAD18KP85CA is a reliable and versatile TVS-diode suitable for a wide range of applications. With its quick-response and energy-dissipating features, it offers an effective way to safeguard against overvoltage transients or spikes. Its low-noise, wide temperature range, and low-impedance performance make it highly suitable for high-voltage applications.
