TVS (Transient Voltage Suppressor) diodes are mainly used to protect power supplies and equipment from damage caused by high and sudden power surges. These components are designed to conduct or shunt away over voltages, in order to prevent damage to sensitive components in the connected equipment. MPLAD36KP28A is one of popular TVS diodes used in a variety of various applications. This article will discuss about the application field and working principle of MPLAD36KP28A.

MPLAD36KP28A is a dual type TVS diode. It has reverse voltage of 28V and maximum power dissipation of 2W. This device has bidirectional capability and is mainly used in protection from transients induced by lightning or inductive load switching. It is ideal for protection of I/O interfaces, data, and common mode lines. It offers a low capacitance in order to protect high-speed interfaces such as USB, DVI, S-Video, HDMI, and Ethernet from damage. This device has an ultra-low leakage current and an extremely fast response time.

The application area of MPLAD36KP28A includes surge protection in automotive and other industrial applications, protection of I/O interfaces and data lines, ESD, and other transient protection applications. It can be used in automotive systems for ABS systems, airbag, power windows, control units, and dashboard sensors. It is also used in consumer electronics, computers, communication systems, motor control, and other industrial equipment. This device is available in SMA and SMB packages.

The working principle of product MPLAD36KP28A is highlighted below.

MPLAD36KP28A is a voltage-dependent device which works based on avalanche breakdown mechanism. When the transient voltage reaches a certain value, the electron-hole pairs generated in the base region of the device lead to an avalanche multiplication. This avalanche effect began as the minority carriers move quickly across the n-type and p-type regions. This avalanche multiplication process results in a large current between the anode and the cathode, thereby diverting the transient voltage from the load.

MPLAD36KP28A has an integrated structure which contains two built-in cells. Each of these cells works independently to protect the load on each side of the diode. The leakages of the two cells are low and are not related to each other. The diode also has improved di/dt performance, making it a viable solution for high-frequency applications. Moreover, the device also has an ultra-fast response time to reduce the RC delay and eliminate any additional ringing.

In conclusion, MPLAD36KP28A is a viable option for applications requiring robust ESD and transient protection. It has reverse voltage of 28V and maximum power dissipation of 2W. The device can be used in a wide variety of applications such as automotive, consumer electronics, computers, communication systems, and more. It is good for protection of I/O interfaces, data, and common mode lines, due to its low capacitance. It has bi-directional capability and an ultra-fast response time. The working principle of this device is based on avalanche breakdown mechanism.
