The MPLAD15KP70AE3 is a series of Transient Voltage Suppressor (TVS) Diodes from ON Semiconductor. These components are used in a variety of application to provide surge protection for connected devices or circuits, as well as protection against Electrostatic Discharge (ESD). The MPLAD15KP series is designed for a variety of applications in the automotive industry due to its wide operating temperature range of -40°C to 125°C and high surge rating. It also provides an increased Peak Pulse Power (PPP) capability and an enhanced ESD protection level for use in harsh environments.

The MPLAD15KP70AE3 device is housed in a small, leadless E3 package and utilizes a Zener element design to clamp transient voltage spikes. The package provides mechanical and electrical stability, as well as a compact solution that can be soldered directly onto the circuit boards. The device is a low capacitance device that is designed to support high-speed data communications and other sensitive circuits. It provides fast turn-off time and low clamp voltage at a peak pulse power capability of 15KW.

The working principle of the MPLAD15KP70AE3 is based on the Zener element. It has the ability to “clamp” the voltage that exceeds its breakdown spike voltage, and it also has the advantage of having a fast response time to transient voltage spikes. During normal operation, the diode remains in the forward blocking state until a voltage spike that exceeds its clamping voltage is detected. When a surge or transient voltage is detected, the device will begin to conduct current, allowing it to safely “clamp” the voltage spike. The voltage at the diode terminals will never exceed its breakdown voltage, thereby providing reliable protection to the connected devices or circuits.

The MPLAD15KP70AE3 is widely used in applications such as power supplies, computers, automotive systems, and data communications. Its robust design provides excellent surge protection performance while keeping the total board area to a minimum. It is designed to protect sensitive components from damaged caused by overvoltage, electromagnetic interference (EMI), and electrostatic discharges (ESD). It is also designed for use in flat, ground-coupled circuits, and reconnection systems which help reduce the effect of voltage drops.

The MPLAD15KP70AE3 is an ideal choice for a wide range of applications due to its high surge capability, wide operating temperature range, small size, and reliable protection against over voltage, EMI, and ESD. Its fast reaction time and low clamp voltage enable it to offer protection in harsh environments to maintain the performance and reliability of connected devices and circuits for many years.
