Panasonic Industry has recently introduced a new PhotoMOS® relay in a miniature WSSOP package designed for measuring, testing and medical equipment. It belongs to the successful series of so-called Low CxR PhotoMOS®. AQY231R1WY (1Y) have an optimized, very low product of C and R of the output MOSFETs. The first relay of this series operates at 40V, 350mA and available in 1FormA contact arrangement.

MOSFET relays play a crucial role in the measurement and test equipment market due to their speed, efficiency, and reliability. As a trusted manufacturer, Panasonic Industry ensures that their innovative products can effectively serve the above requirements to meet the needs of various industries and applications.

PhotoMOS® Relays are increasingly used in various industrial applications due to their unique characteristics and advantages over traditional electromechanical relays. Here are some key features of the brand new WSSOP relay:

• New Compact Package: WSSOP reduces the mounting area by 89% compared to conventional products. This contributes to the miniaturization of equipment giving the customer the advantage to build more resource and be cost efficient.
   
• High temperature operation: Guaranteed to operate at a maximum ambient temperature of +125°C, the new PhotoMOS® relay is ideal for use in high-temperature environments like semiconductor testers and burn testers. For comparison, conventional relays are only able to handle up to +85°C.
   
• High sensitivity: The current required to operate the WSSOP relay is only 1.0mA, which is 1/3 of the 3.0mA required by the conventional product, demonstrating a reduction to 1/3 of the power consumption, which contributes to energy saving of the equipment.
   
• High speed operation: The WSSOP PhotoMOS® relay operates on T_on, typ. 0.025ms; T_off typ. 0.15ms
   
• High frequency characteristics: Most importantly, the PhotoMOS® HS WSSOP comes with excellent high-frequency characteristics enabling transmission without breaking high frequencies. This product guarantees an insertion loss of 50 Ω, within 3dB at ~10 GHz.

Chaithra Bhat Beedubail, Product Manager at Panasonic Industry Europe, comments: “With the new PhotoMOS relay we have developed a product for our customers, which is offering a unique, miniature design without making any compromises in terms of performance. The relay is particularly suitable for a variety of applications in test equipment - such as IC tester, board tester or probe cards - measurement equipment like Multimeters or Multiplexer and medical equipment, for example X-ray machines, ultrasonics and CT scanners. We are excited to expand our PhotoMOS family with this exciting new addition.”
