MPLAD15KP78CAE3

TVS (Transient Voltage Suppression) diodes provide cost-effective solutions for protecting sensitive electrical systems against voltage spikes and overvoltage events. The MPLAD15KP78CAE3 is a uni-directional, surface mount TVS diode from Texas Instruments that offers protection against surges and transients of up to 15kV (stand off voltage of 14.1V).

Application

The MPLAD15KP78CAE3 is designed for applications that require a high peak pulse current capability and low leakage current in extreme environmental conditions. It\'s most suitable for use in computers, industrial and consumer electronics, automotive and avionic systems , and telecommunications equipment. Its features provide ultra-fast clamping response, low clamping voltage, and low capacitance. It also provides protection for conductive and inductive lines and for surge and transients to longer wire lengths or lines that are tapped.

Working Principle

As soon as the voltage exceeds the standoff voltage, the MPLAD15KP78CAE3 TVS diode begins to conduct and suppress the surge or transient voltage. This motion begins at the peak clamping voltage, and the voltage is rapidly reduced. When the voltage returns to the safe level, the diode is in a non-conducting state. The clamping voltage of the MPLAD15KP78CAE3 is typically 5.5 volts.

The device is designed to protect against various surges and transients including Electrostatic Discharge (ESD), ElectroMagnetic Interference (EMI), lightning, and other overvoltage events. It is available in two package configuration options – the SC15KP71 and the TS13KP71, each with an 8-lead package that is suitable for lead-free reflow soldering and provides a unique thermal design that prevents thermal runaway.

Conclusion

The MPLAD15KP78CAE3 TVS diode from Texas Instruments is an efficient and low-cost solution for protecting sensitive electronics from overvoltage events. It offers fast clamping response, low clamping voltage, and low capacitance, which makes it ideal for a wide range of applications such as computers, consumer electronics, automotive and avionic systems, and telecommunications equipment. It also provides protection from ESD, EMI, and lightning and other transients and surges.
