MAPLAD18KP10A

TVS - Diodes

MAPLAD18KP10A is a voltage-dependent transient suppression diode designed specifically for transient voltage suppression (TVS) applications. Its design and construction make it highly suitable for use in circuits that require high power transients protection, due to its ability to absorb large transient energy. It is one of the most advanced TVS diode designs available, and is widely used in all electronic protection applications, from consumer electronics to industrial applications.

Application Field

MAPLAD18KP10A is generally used in circuits where a high degree of transient protection is required. It is especially suitable for protecting against transients such as lightning, inductive kickback, or radio frequency interference (RFI). As such, it is suitable for use in high-powered consumer electronic devices, industrial electronic equipment, and automotive electronics, including engines, alternators, and sensors.

The MAPLAD18KP10A offers superior protection compared to other transient suppression diode designs, making it an ideal choice for applications that require protection against severe transients. It is capable of withstanding high voltage transients, thus providing optimal protection for sensitive electronic devices and components.

MAPLAD18KP10A is also suitable for use in high surge and power applications, as it can absorb large transient energy. Its construction also ensures that it is highly robust against mechanical shock, making it suitable for use in more rugged applications.

Working Principle

The MAPLAD18KP10A works according to the principle of breakdown voltage, in which the diode can dynamically adjust its reverse breakdown voltage according to the transient current that is applied. This process is known as a \'dynamic Zener\' action, as the diode is able to adjust its voltage up to 24 volts in just a few nanoseconds. When the reverse breakdown voltage of the diode is reached, the diode starts to conduct current, and the current is then absorbed by the diode.

The ability to dynamically adjust its reverse breakdown voltage is one of the main advantages of the MAPLAD18KP10A. This allows it to provide reliable protection against transients of varying amplitude, as well as allowing the diode to tailor its performance to the requirements of the application. This also ensures that the diode does not degrade or fail due to repeated exposure to transients, which can happen with other TVS diode designs.

In addition, the MAPLAD18KP10A also features a built-in thermal protection mechanism, which can reduce the current absorption rate in the event of a thermal overload. This helps to protect sensitive circuit components, ensuring that the diode will not fail due to excessive temperature.

Conclusion

The MAPLAD18KP10A is a highly versatile transient suppression diode, designed specifically for TVS applications. It is capable of providing reliable protection against transients of varying amplitude, and features a thermal protection mechanism to help protect against overloading. Overall, it is an excellent choice for use in circuits that require high power protection.
