TVS - Diodes are important components in electronic circuits, designed to protect against over-voltage transients that can damage sensitive components, such as signal processors and memory devices. The MPLAD15KP75A is a type of diode in the TVS family that is especially designed to provide robust protection against lightning surges for residential and commercial applications, due to a high peak pulse power rating of 15,000W and a 75V standoff voltage.

The MPLAD15KP75A is a unidirectional device, meaning it is specifically designed to protect against transients with one polarity only, typically transients with a positive polarity. Therefore, it is constructed with an N-channel (negative polarity), and P-channel (positive polarity) for bi-directional applications. The diode has a low dynamic impedance of less than 1 ohm, which allows it to reduce the voltage impact of surges quickly.

The MPLAD15KP75A is made of a dual-MOSFET design that offers a low voltage clamping level and a low leakage current, a very important feature since surge protection circuits need to remain inactive during normal operation to provide the most efficient protection. When operated, the device quickly clamps the line voltage to the standoff voltage during transient events. It also features a low breakdown voltage and fast response time, making it suitable for protecting sensitive devices.

The MPLAD15KP75A is suitable for environmental and operating conditions ranging from –55°C up to +125°C, meaning it can safely be used in either very cold or very hot temperatures. The device also offers excellent surge capability and high-energy absorption. All of this in an ultra-small package that measures just 7.5x7.5mm with no external components needed.

The MPLAD15KP75A is perfect for industrial applications that require reliable surge protection. These applications may include communications, devices with digital inputs, data interfaces, and battery operated systems. With its robust design, reliable performance and reasonable price, the MPLAD15KP75A is a great choice for protecting sensitive electronic devices.
