Renesas Electronics Announces World’s Smallest Photocouplers for Industrial Automation and Solar Inverter Applications

RV1S92xxA and RV1S22xxA 8.2mm Creepage Photocouplers Reduce PCB Mounting Area by 35 Percent to Maximize Board Space

12 Dec 2019

TOKYO, Japan ― Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today announced five new 8.2mm creepage photocouplers that are the world’s smallest isolation devices for industrial automation equipment and solar inverters. With a package width of 2.5mm, the RV1S92xxA and RV1S22xxA photocouplers reduce PCB mounting area by 35 percent compared to competitive couplers. They help designers shrink equipment size, increase robot axes, and improve factory floor productivity. They also meet the needs of the zero-energy house that requires smaller solar equipment for more installations in limited space. The RV1S92xxA and RV1S22xxA photocouplers are ideal for DC to AC power inverters, AC servo motors, programmable logic controllers (PLCs), robotic arms, solar inverters, and battery storage and charging systems.

The RV1S9260A 15 Mbps communications coupler and RV1S9213A intelligent power module (IPM) driver are the first photocouplers to use tiny LSSO5 packages with a 0.65mm pin pitch, half the pitch of conventional packages. With a package height of 2.1mm, the photocouplers can be directly mounted on the backside of a PCB, freeing up valuable space for topside mounted components. Three times infrared reflow soldering provides maximum flexibility. The RV1S92xxA photocouplers’ electric isolation and high CMR noise rejection (50 kV/µs) protects low voltage microcontrollers and I/O devices from high voltage circuits when transferring high-speed signals.

The RV1S2281A and RV1S2211A are DC input and low DC input, transistor output photocouplers, and the RV1S2285A is an AC input, transistor output coupler. The RV1S22xxA devices also provide 8.2mm creepage distance, 2.5mm package width and 2.1mm package height. They come in LSSOP packages with a 1.30mm pin pitch. All five photocouplers deliver 5000 Vrms reinforced isolation and high temperature operation to withstand harsh operating environments. The RV1S92xxA and RV1S22xxA photocouplers support 200V and 400V systems with reinforced insulation to meet industrial safety standards. All five devices adhere to the strict UL61800-5-1 standard for motor drive equipment, and the UL61010-2-201 standard for control devices such as PLCs.

“The RV1S92xxA and RV1S22xxA photocouplers give designers a variety of functions and the layout flexibility to significantly reduce equipment size and maximize factory floorspace,” said Philip Chesley, Vice President, Industrial Analog and Power Business Division at Renesas. “Our isolation devices also meet the stringent safety requirements of the UL61800-5-1 and UL61010-2-201 standards, enabling manufacturers to design a new generation of high voltage systems for their smart factories.”
