New 8.2mm creepage IGBT drivers and IPM driver reduce PCB mounting area by 35 per cent, which maximises board space

Measuring a mere 2.5mm x 2.1mm, here’s introducing three new devices designed for operation in harsh industrial automation equipment, solar inverter and EV charger operating environments. As an extension to Renesas Electronics’ family of 8.2mm creepage photocouplers, the new additions claim to be the smallest optical isolated IGBT drivers and intelligent power module (IPM) driver that reduces PCB mounting areas up to 35 per cent.

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

“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 RV1S9209A, RV1S9231A and RV1S9207A photocouplers are available now from Renesas’ worldwide distributors.
