Mixed technology is a process by which different materials, methods and techniques are used to fabricate electronic assemblies, such as printed circuit boards and other electronic components. This technique is often used in the development of advanced products, due to the complexity of the component assembly process. In the case of the ESDU02A5V5R17V product, the mixed technology approach is used to create a rapid and localised high-voltage transient protection device. The device utilises both silicon MOSFETs and diode technology to protect sensitive electronics.

The ESDU02A5V5R17V is designed to provide fast and effective high-voltage transient protection from surges, over-voltages, static dissipations, and ESD events. It is capable of providing surge protection up to 18 kV in peak pulse current, and can respond in less than 8 nanoseconds, when faced with a 10/1000 μs pulse. It is also capable of standing off and clamping voltages from 15 to 30 VDC. This device has a very low capacitance, which enables it to be used in a range of applications such as automotive electronics, industrial power supplies, computers, telecommunications and the like.

The working principle of the ESDU02A5V5R17V can be broken down into several components. The device consists of two paralleled MOSFETs which act to dissipate the energy unleashed by high-voltage transients. The MOSFETs are integrated with a zener diode and two ultra low capacitance TVS diodes, both of which have a low clamping voltage. The TVS diodes absorb the voltage spikes of up to 30VDC, while the zener diode safely clamps the voltage to a predetermined voltage. In addition, the ESDU02A5V5R17V employs a driver circuit which is able to sense and detect the voltage level of the circuit and then quickly turn on and off the MOSFETs in order to dissipate energy.

The ESDU02A5V5R17V is widely used in a variety of applications such as automotive electronics, industrial power supplies, computers, telecommunications and the like. Its use of both low-capacitance TVS diodes and a zener diode allows it to react rapidly to voltage transients and reduce their impact on sensitive electronics. The robust construction and fast response make it ideal for protecting a wide variety of components and circuitry from potentially damaging voltage transients.
