Renesas has expanded its family of 8.2mm creepage photocouplers with three new devices designed for operation in harsh industrial environments.
Measuring a mere 2.5mm x 2.1mm 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 new RV1S9231A 2.5A output and RV1S9207A 0.6A output IGBT drivers and RV1S9209A active high output IPM driver come in low-profile LSSO5 packages with a 0.65mm pin pitch, deliver 5,000 Vrms isolation voltage, and support high temperature operation up to 125°C to withstand the harsh operating environments. The photocoupler trio also supports 200V and 400V systems with reinforced insulation to meet stringent industrial safety standards, adhering to the strict UL61800-5-1 standards for motor drive equipment.
