Tiny photocouplers for industrial automation and solar inverters

New Products |
By Jean-Pierre Joosting

Renesas Electronics Corporation has expanded its family of 8.2-mm creepage photocouplers with three new devices designed for operation in harsh industrial automation equipment, solar inverter, and EV charger operating environments. Measuring a mere 2.5- x 2.1-mm in an LSSO5 package, the world’s smallest optical isolated IGBT drivers and intelligent power module (IPM) driver reduce PCB mounting areas by up to 35 percent compared with other devices on the market.

“Industrial equipment and green energy system manufacturers are currently facing two core challenges. Equipment needs to get smaller, requiring downsizing for factory floor efficiency and higher functionality equipment within the same board size, while at the same time, safety standards are getting stricter,” said Philip Chesley, Vice President, Industrial and Communications Business Division at Renesas. “Our expanded portfolio of small isolation devices offers customers greater layout flexibility with more options to enable longer secured creepage distance for high-voltage inverter control applications.”

The latest RV1S9231A 2.5-A output and RV1S9207A 0.6-A output IGBT drivers and RV1S9209A active high output IPM driver come in low-profile LSSO5 packages with a 0.65-mm pin pitch, deliver 5,000 Vrms isolation voltage, and support high temperature operation up to 125°C to withstand the harsh operating environments. The trio of photocouplers also supports 200-V and 400-V systems with reinforced insulation to meet stringent industrial safety standards, adhering to the strict UL61800-5-1 standards for motor drive equipment.


Renesas has identified and created a system architecture for various applications where the RV1S92xxA family of products adds tangible value in the system. For instance, a new AC Drives / GP Inverters “Winning Combination” featuring the RV1S92xxA family of products enables customers to downsize their industrial equipment and inverter systems that meet UL61800-5-1 standard. Winning Combinations are vetted system architectures made from mutually compatible devices that work together seamlessly.
