MPLAD36KP58CA Application Field and Working Principle

MPLAD36KP58CA is a Transient Voltage Suppressor (TVS) diode designed to protect against damage from power supply transients, in circuits where important components are exposed to high voltages. It features low capacitance levels, which means it has an extremely fast response time, and a breakdown voltage of 36V, which allows it to achieve a maximum clamping voltage of 58V. It is also rated for up to 1KW Power Dissipation.

The main application field for the MPLAD36KP58CA is automotive electronic systems, such as vehicles with GPS guidance systems, engine control modules, diagnostic tools, and other devices which require protection from power transients. It is particularly suited for applications where the power spikes may be generated from multiple sources, such as when the engine is running and the alternator is charging the battery.

The MPLAD36KP58CA operates based on a simple principle. When the input voltage rises above the device\'s breakdown voltage of 36V, a metal oxide layer is attracted to the anode, creating a path for current to flow from the anode to the cathode. This action limits the output voltage and current to a safe level. Once the voltage drops back below the breakdown voltage, the metal oxide layer dissipates and normal operation is resumed.

In addition to its fast response time, the MPLAD36KP58CA also features various safety mechanisms to protect against overvoltage situations. It features an integrated protection diode which clamps the voltage to around 48V, and a transient protection diode which turns on at around 25V, reducing voltage spikes to less than 10V. It also has an integrated thermal switch which turns off the current when the temperature limit is exceeded, preventing damage to the device.

The MPLAD36KP58CA is a robust, reliable device that provides efficient protection against damaging transients. It can be used in a wide variety of automotive electronics, including engine control modules, navigation systems, and diagnostic tools. It is rated for up to 1KW power dissipation, has a low capacitance level, and allows for a maximum clamping voltage of 58V. Its integrated safety mechanisms ensure that power spikes are kept to a minimum, and it is suitable for protecting components from high voltage transients.
