Automated test equipment, or ATE, helps to ensure the quality and functionality of electronic components. These complex machines perform many tests at high speeds and therefore demand reliable and efficient switching mechanisms. Omron’s Metal-Oxide-Semiconductor Field-Effect Transistor relays have entirely transformed the efficiency of ATE.

Read on to learn how Omron MOSFET Relays improve automated test equipment efficiency. 

What Are MOSFET Relays?

A Metal-Oxide-Semiconductor Field-Effect Transistor relay is an electronic switch for switching and connecting signals without physical contact. Unlike traditional mechanical relays, MOSFET relays utilize semiconductor technology, combining the characteristics of mechanical relays and solid-state devices. This hybrid nature offers several advantages in various applications, such as automated test equipment, semiconductor inspection systems, measurement devices, and security equipment.

The Impact of Omron MOSFET Relays on ATE Performance

The implementation of Omron MOSFET relays in ATEs translates into several quantifiable benefits:

Minimizing Leakage Current

Leakage current can distort test results, especially in high-accuracy applications. Omron MOSFET relays are designed to minimize leakage current, achieving a maximum of less than 1pA. This reduction in leakage current means that the device under test (DUT) receives accurate signals, leading to more reliable test outcomes.

Stable ON Resistance

The relays offer stable ON resistance, which is necessary for maintaining consistent signal quality during testing. This guarantees that the signal integrity is preserved, leading to more accurate measurements and reliable data.

Compact Design

Space-saving components are precious in high-density testing environments. The Omron relays come in a compact package, allowing for more relays to be fitted onto a single board. This compact design helps optimize board space without compromising on performance.

SPDT Contact Form

Traditional MOSFET relays typically offer a single pole single throw (SPST) contact form, limiting their functionality. Omron MOSFET relays provide a single pole double throw (SPDT) contact form in a single package. This added functionality gives more versatility to ATE systems, allowing for more complex switching configurations.

Long Life and Reliability

The Omron MOSFET relays are designed for long life and reliable performance, reducing the need for frequent replacements. This longevity is particularly beneficial in ATE systems, where downtime for maintenance can be costly and disruptive.

Low ON and OFF State Capacitance

These relays are available in models with low ON-state resistance and low OFF-state capacitance, catering to different application needs. Low ON-state resistance minimizes power loss, while low OFF-state capacitance ensures minimal signal interference when the relay is not in use. These features contribute to overall better performance and efficiency in ATE systems.

High-Frequency Switching

Omron MOSFET Relays are designed for high-frequency applications, providing reliable switching for RF signals. These relays can handle signals up to 1GHz, 3GHz, and 8GHz, making them suitable for a wide range of high-frequency testing scenarios.

Low-Profile and Surface Mount Packages

The relays come in low-profile and surface-mount packages, saving valuable board space in ATE systems. This compact design allows more relays to be used in high-density testing setups, optimizing available space without compromising performance.
