MPLAD18KP70AE3 application field and working principle

The MPLAD18KP70AE3 is an unidirectional lowcapacitance transient voltage suppressor, often used in digital applications. Developed by STMicroelectronics, it is designed to offer protection against surges and voltages that exceed the specified MDC. TheMPAD18KP70AE3 can protect voltage sensitive electronics against ESD, EFT, surge, and more.

The MPLAD18KP70AE3 is a diode suitable for AC/DC operation and operates between 7 and 18V. It has a wide operating temperature range from -60°C to 125°C and offers high-energy discharge capabilities. It also includes a low-capacitance diode array to provide immunity to high-frequency signals. The device is also available in a TO-252 (DPAK) package.

The TVS diode of the MPLAD18KP70AE3 contains three terminal technology that offers protection against overvoltage transients, EMI/RFI interference, and electrostatic discharges. This particular device is designed for digital electronic systems, such as ones used in automotive, consumer, industrial, communications, and medical applications.

The MPLAD18KP70AE3 works by clamping the voltage, sinking the excess electrical current away from sensitive components, and providing an additional path for transient current. The internal diodes in the device act like a switch, only conducting current when the voltage exceeds the avalanche voltage of the TVS diode.

The MPLAD18KP70AE3 also offers enhanced protection against pulse current and has low parasitic capacitance in order to prevent damage to sensitive analog and digital circuits. With regard to ESD and EFT protection, the device is designed to protect against pulses up to ±25kV.
