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.”
