TVS (Transient Voltage Suppressor) diodes are a type of semiconductor component specifically designed to protect sensitive electrical devices from high voltage spikes. The MAPLAD36KP24A is one such device, a uni-directional diode specifically designed for use in motor control applications. In this article, we will discuss its application fields and working principle.

Application Field:

The MAPLAD36KP24A is a great option for applications such as AC and DC motor controls, motors with rotating fields or permanent magnets, PLCs, and computer control systems. This type of diode can handle a wide range of spike voltages, so it’s suitable for DC motors with higher operating voltages. It also provides good protection from overvoltage related failures, and it can help reduce the risk of a short in the system.

In addition, since the diode offers insulated mounting, it’s easier to mount onto a circuit board. The component is designed to be compatible with standard circuit board breakouts, so it requires minimal PCB routing. Furthermore, since the device has a low response time, it is suitable for use in applications that require very fast response times.

Working Principle:

The MAPLAD36KP24A is a uni-directional TVS diode that works by providing protection from overvoltage by redirecting excess energy. It consists of two p-n junctions connected in series, with a small reverse bias voltage applied to one of the junctions. When a high enough voltage is applied, the diode’s reverse bias voltage is overcome and the reverse current starts flowing. The excess energy is then redirected away from the protected circuit, which prevents damage to the circuit.

The MAPLAD36KP24A also provides surge protection. This is done by the incorporation of a gas discharge tube (GDT) that operates as a circuit breaker, preventing further surge voltage from entering the protected circuit. This ensures that the protected circuit is not damaged by any sudden increase in voltage.

The MAPLAD36KP24A also has a high reverse bias voltage rating of up to 36 kV, which helps protect against electromagnetic interference (EMI). This helps to ensure that the device will not be damaged by high frequency electrical signals that can cause interference in the system circuits.

Conclusion:

The MAPLAD36KP24A is a reliable and cost-effective TVS diode that is suitable for protecting sensitive electrical systems from overvoltage or spikes in voltage. It offers a wide range of voltage protection, surge protection, and EMI protection, which makes it a great choice for many applications. If you are looking for an effective way to protect your system from overvoltage related failures, this device is definitely worth considering.
