TVS - Diodes, or Transient Voltage Suppressors, are a type of device designed to protect electrical circuits from potential damage caused by voltage transients. The MAPLAD36KP300CA, commonly referred to as a ‘crowbar’ diode, is a bidirectional device that can protect up to 36V DC load lines.

Application Field

The MAPLAD36KP300CA is designed primarily for application in battery operated devices such as portable computers, cell phone handsets and medical electronics. The device provides bidirectional peak overvoltage protection for up to 36V DC load lines. It is also suitable for AC applications such as AC adapters.

Working Principle

The MAPLAD36KP300CA works by controlling and limiting the voltage that a circuit receives by using a voltage regulator. The device contains a clamping control circuit that monitors the input voltage and will close the circuit if the voltage is above the preset threshold. Once the circuit is closed, the reverse current flow is limited to a small amount, thus protecting the circuit from any potentially damaging overloads.

When the input voltage is below the preset threshold, the MAPLAD36KP300CA allows the current to flow freely. This ensures that the electrical circuit is not starved of power, yet still maintained at a safe level. If the input voltage exceeds the threshold, the device will initiate a reverse electro-motive force (EMF) process, which will swing the voltage across the diode rapidly and clamp the excess voltage to another potential.

In comparison to other TVS diodes, the MAPLAD36KP300CA offers enhanced performance, due to its higher forward voltage and larger peak power handling capability. The device also features built-in thermal compensation, which ensures the device will respond quickly to voltage transients, regardless of temperature conditions. This makes it ideal for applications where the temperature of the environment varies greatly.

The MAPLAD36KP300CA also offers superior ESD protection for electrical and electronic circuits, due to its bidirectional low-voltage design. The diode is capable of handling 1500W peak pulse power, while providing transmission line protection up to 5kV in both directions. This makes it ideal for use in systems such as automotive electronics, consumer electronics, telecom systems, and medical equipment.

Overall, the MAPLAD36KP300CA is a highly reliable and versatile device, capable of providing reliable protection for electrical circuits, while also offering superior ESD protection. By monitoring the input voltage and limiting the current flow, it offers enhanced protection and can prevent damage due to potentially damaging power spikes and voltage transients. As such, the MAPLAD36KP300CA is well-suited for a wide range of applications, from simple consumer electronics to more complex systems.
