Transient Voltage Suppressors (TVS – Diodes) is an important device for protecting the critical components of a system from transient voltage generated from electrostatic discharge (ESD). The MPLAD36KP300CAE3, from Littelfuse Company, is a Silicon Diodes Array composed of three discrete low capacitance, low leakage transient voltage protection diodes.

The MPLAD36KP300CAE3 has an anode side pin configuration of anode A–B–C and a cathode side pin configuration of cathode C–B–A. It can provide ESD protection up to 32 kV contact discharge per IEC 61000-4-2 and 30 kV air discharge per IEC 61000-4-5. The maximum peak pulse power dissipation is 300 W in order to protect against voltage, current, and power induced electrical surges.

The application fields of the MPLAD36KP300CAE3 are found in many electronics applications in the markets of automotive, consumer electronics, and industrial electronics. It can be used on the point of load-switchers, accelerometers, and other electronic components that are affected by transient voltages.

Transient voltage protection diodes of the MPLAD36KP300CAE3 can provide externally triggered surge current protection with high-level accuracy. The working principle of the device lies in its ability to pass current in the forward direction with a known voltage drop and allow for conduction in the reverse direction at a higher voltage. Its breakdown voltage is specified such that it will limit the reverse voltage across the device during a transient surge.

When a transient voltage is applied, the overvoltage tends to reverse bias the device. This causes carriers to flow across the junction, leading to a current in the opposite direction to that in the forward saturation region. The avalanche breakdown current contributes to the steady state current, which will change abruptly when a transient voltage is applied. Since the forward voltage drop across the diode is low, it will limit the voltage across the device and reduce the energy dissipated during a transient voltage surge.

The MPLAD36KP300CAE3 device is designed to protect sensitive electronic components from surge events that may cause damage. With its surface mount package and multiple pin setup, it can provide enhanced protection from transient voltages in a wide range of applications. It is at the forefront of protection technology, allowing system designers to save time and money in the development process.
