Miniature WSSOP PhotoMOS elevates measurement and test equipment

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) and 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-saving and be more 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 Ton, typ. 0.025ms; Toff

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.”
