TVS (transient voltage surge) diodes are essential components for protection in most electronic systems. They provide immunity to voltage and current surges caused by lightning, voltage spikes, ground loops, and other electrical events. The MAPLAD30KP110CAE3 is a TVS diode designed for ESD, EFT, and surge on low capacitance lines.

The MAPLAD30KP110CAE3 offers a low capacitance of 0.3pF, a low clamping voltage of 17 volts, and a high peak power rating of 11kW. It is designed to withstand up to 17,000A of surge current. The product is RoHS-compliant and ideal for safety-critical automotive applications such as airbag controllers, restraint controllers, and car light modules.

The working principle of the MAPLAD30KP110CAE3 is based on avalanche breakdown, which is a property of semiconductors; it occurs when the electric field across a semiconductor is increased to a level such that the electrons in the material are accelerated to a velocity great enough to cause further ionization of the medium. This leads to an increase in current, and the voltage across the diode also increases as a result. In the case of the MAPLAD30KP110CAE3, this is followed by an electrical contact with the anode and cathode of the diode, resulting in the clamping of the voltage.

The MAPLAD30KP110CAE3 also provides high protection for low frequency transient events. It is designed to handle high peak pulse current levels, while maintaining a relatively low clamping voltage at low pulse rise and fall times. The product is fast enough to protect high frequency signal lines such as serial communication and USB. It has a fast response time of less than 1ns.

The MAPLAD30KP110CAE3 is available in an easy-to-assemble 2x1mm DFN package and is suitable for a wide range of reflow processes. The product is designed to provide an electrical short circuit to ensure the device does not fail in the event of an ESD or surge event, and it also provides a dielectric isolation layer to provide additional protection against high voltage surges.

The MAPLAD30KP110CAE3 is a highly reliable and robust TVS diode ideal for use in a wide range of safety-critical automotive applications. Its low capacitance, low clamping voltage, and fast response time make it ideal for protecting low capacitance lines from voltage and current surges caused by lightning, voltage spikes, and ground loops.
