RV1S92xxA & RV1S22xxA Smallest 8.2mm Photocouplers

Renesas Electronics introduced 5 new 8.2mm creepage photocouplers namely RV1S9260A, RV1S9213A, RV1S2281A, RV1S2211A, and RV1S2285A which are claimed to be the world’s smallest isolation devices for industrial automation equipment and solar inverters with a package width of only 2.5mm. The RV1S92xxA and RV1S22xxA photocouplers can reduce the PCB mount area by 35% compared to the other photocouplers available in the market, they reduce the equipment size, increases robot axes and improve factory floor productivity.


Features of RV1S92xxA

  • Uses tiny LSS05 packages with a 0.65mm pin pitch which is half of the convention package
  • Package height of 2.1mm for backside mounting on the PCB
  • Three times infrared reflow soldering
  • Designed with electric isolation and high CMR noise rejection(50kV/ µs)
  • Protects low voltage microcontrollers and I/O devices from high voltage circuits when transferring high-speed signals.


Features of RV1S22xxA

  • RV1S2281A and RV1S2211A are DC input and low DC input, transistor output photocouplers
  • The RV1S2285A is an AC input, a transistor output coupler
  • Provides 8.2mm creepage distance, 2.5mm package width, and 2.1mm package height
  • Come in LSSOP packages with a 1.30mm pin pitch


All five photocouplers have the ability to deliver 5000 Vrms reinforced isolation and equipment operation to withstand harsh operating environments. They can support 200V and 400V systems with reinforced insulation to meet industry 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 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 photocouplers are available with the worldwide distributors at the following price for 1000 unit quantities, RV1S9260A - $0.64 USD, RV1S9213A- $0.53 USD, RV1S2281A- $0.17 USD,RV1S2211A - $0.17 USD  and RV1S2285A - $0.40 USD.For more information respective product page of each of the Photocoupler on the official website of Renesas electronics.
