MAPLAD18KP33CA

TVS diodes are widely used in a variety of applications due to their superior electrical and thermal characteristics. Commonly available diodes are single or dual junction, and they can be used in a variety of configurations, such as bridge, flyback, and series-parallel. The MAPLAD18KP33CA is an example of a TVS diode developed by Microsemi.

MAPLAD18KP33CA diodes are designed for applications requiring superior electrical performance and EMI suppression. They have an operating voltage range of 18 volt, a maximum peak surge current rating of 400A, and a maximum continuous operating current of 25A. The thermal derating curves for these diodes indicate that their maximum continuous operating current should reduce by 2A for every 5°C increase in ambient temperature. This feature ensures that electrical performance is not compromised even in challenging operating conditions.

MAPLAD18KP33CA diodes have a maximum reverse recovery time of 6ns, which is ideal for applications requiring fast switching speeds. Additionally, they have a low parasitic inductance and capacitance, which provides improved EMI performance. This is especially beneficial in high-frequency switching applications, which often require good EMI performance.

The MAPLAD18KP33CA diode utilizes a high-temperature resistant, low-loss dielectric material, which provides superior performance in high temperature applications. It also features a low stand-off voltage, which allows the diode to be used in a wide variety of circuit configurations.

MAPLAD18KP33CA diodes have many applications in a variety of fields. They are commonly used in automotive, medical, and commercial/industrial applications, among others. They are also frequently employed in switched-mode power supplies, power converters, and solenoid drivers.

The working principle of MAPLAD18KP33CA diodes is fairly straightforward. They work by offering an extremely low voltage threshold, allowing an external voltage to be connected to the device without causing damage or stressing the components. When the external voltage exceeds the diode’s threshold voltage, the diode will quickly turn on, providing a path for the current to flow through.

Once the external voltage goes below the diode’s threshold voltage, the diode will turn off, preventing the current from flowing. This type of diode is typically used in applications that require fast switching times, such as switching mode power supplies and motor controllers.

MAPLAD18KP33CA diodes are just one example of the many TVS diodes available on the market. These devices are extremely versatile and can provide improved electrical performance, EMI suppression, and temperature protection in any application they are used in.
