The CPC1117NTR is an amazing little solid-state relay that fits into a small 4-pin SOP package. It works very well. This relay was made by IXYS Integrated Circuits. It uses cutting-edge optically coupled MOSFET technology and is a strong option with input/output isolation of 1500 Vrms. In this detailed guide, we’ll talk about the CPC1117NTR’s features, benefits, and uses, as well as its advantages over other relays.

Key Features of CPC1117NTR: Setting the Standard for Relays

In the world of current electronics, the CPC1117NTR is a great example of how new ideas can be put to good use. Its design includes a number of unique features that set it apart from other relays and make it a flexible and reliable choice for a wide range of uses. Let’s look more closely at these key features, each of which helps the CPC1117NTR work so well:

Optically Coupled Output: Precision and Reliability

The CPC1117NTR has a cutting-edge optically linked output system that makes sure switching is accurate and reliable. The relay’s output is controlled by an infrared LED, which is known for how well it works. This technology gets rid of the need for actual contacts, which makes relays last longer and need less maintenance. Because of this, the CPC1117NTR has faster response times, less signal distortion, and longer life. This makes it perfect for applications where accuracy is very important.

Space-Efficient Design: Maximizing Board Space

The CPC1117NTR is one of the smallest relays in the world because IXYS Integrated Circuits used cutting-edge double-molded vertical construction packing. This space-saving design is a big deal for modern electronics because it saves a lot of boardroom. Engineers can now improve their designs, putting more utility into tight spaces and pushing the limits of what is possible in small systems.

High Isolation: Protecting Your Circuits

With an impressive 1500 volts of input and output isolation, the CPC1117NTR provides strong security. This amount of isolation is very useful in situations where signal integrity, safety, and protection from electrical noise are important. Whether it’s for industrial automation, medical devices, or high-voltage systems, the high isolation of the CPC1117NTR keeps sensitive components safe from outside interference. This makes your circuits more reliable as a whole.

Energy Efficiency: Minimizing Power Consumption

In this day and age of designing for energy efficiency, the CPC1117NTR stands out as a great way to save energy. Its MOSFET switches and solar die work very well and use the least amount of power possible. This not only lowers the amount of energy your system uses, but it also produces less heat. The result is a cooler place to work, which makes components last longer, reduces the amount of cooling needed, and improves the general reliability of the system.

The CPC1117NTR is a great choice for engineers and designers who want a reliable, small, and efficient relay because it has all of these key features. As we learn more about this relay in the next parts, we’ll find out how it can be used, what makes it better than other relays, and important installation and performance tips. The CPC1117NTR isn’t just a relay; it’s a flexible option that makes your projects more efficient, more accurate, and better use of space.

Input/Output Isolation: Why It Matters

The CPC1117NTR’s input/output isolation of 1500 Vrms is a very important trait, especially when safety and signal integrity are very important. Isolation keeps the input and output circuits from talking to each other in ways that aren’t wanted. This protects sensitive parts and makes sure the system works well. This amount of separation is especially useful in high-voltage and industrial settings.

Advanced Technology

● Optically Coupled MOSFET Technology

At the core of the CPC1117NTR is a technology called an optically linked MOSFET. This new method combines the benefits of optical coupling with the ability of MOSFETs to switch. The result is a relay that can switch quickly and precisely without the problems that come with mechanical contacts.

● OptoMOS Architecture: IXYS Innovation

The performance of the CPC1117NTR is based on the patented OptoMOS design from IXYS Integrated Circuits. This design makes sure that the on-state resistance is low, that the device works quickly, and that it is very reliable. The photovoltaic die controls the MOSFET switches successfully, so signals can be sent without having to make direct electrical contact.

● Efficiency and Performance

The CPC1117NTR is very efficient, which makes it a great choice for apps that try to save energy. The low resistance in the “on” state means that less power is lost during the operation, which means less heat is made and the relay is more reliable overall. Its great performance is also helped by the fact that it can switch between tasks quickly.

● State-of-the-Art Vertical Construction Packaging

The new double-molded vertical construction package from IXYS Integrated Circuits changes the way relays are made. This method of packing not only gives the relay a small size but also makes it last longer by protecting it from the environment and mechanical stress.


● The World’s Smallest Relays: CPC1117NTR’s Compact Design

The CPC1117NTR is small, which is one of its best features. It is one of the smallest switches you can buy because it has a double-molded vertical construction package and a small form factor. This size advantage opens up new options for uses where there isn’t much room on the board.

● Board Space Savings: Comparison with Competitors

The CPC1117NTR saves a lot of board room and is at least 20% more efficient than larger 4-pin SOP relays. This benefit not only makes it easier to make more efficient PCB designs but also makes the whole system smaller, which is a very important factor in modern electronics.

● The Importance of Miniaturization in Electronics

The need for smaller, lighter, and more efficient gadgets is driving the trend toward miniaturization in electronics. The CPC1117NTR fits right in with this trend, so engineers can make systems that are smaller and lighter without sacrificing speed.

CPC1117NTR Applications

Real-world Use Cases for CPC1117NTR

The CPC1117NTR finds application across various industries and scenarios. Some notable use cases include:

  • Industrial Automation:Reliable switching and isolation make the CPC1117NTR ideal for control systems in manufacturing and process automation.
  • Medical Devices:The relay’s compact design is advantageous in medical devices where space is limited and isolation is crucial.
  • HVAC (Heating, Ventilation, and Air Conditioning):Efficient switching and high isolation make the CPC1117NTR suitable for HVAC control applications.


As we conclude this guide, it’s clear that the CPC1117NTR is not just one of the world’s smallest relays; it’s a symbol of progress, efficiency, and reliability.
