Renesas RV1S9209A, RV1S9231A and RV1S9207A photocouplers

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

The 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 5000 V_rms isolation voltage and support high-temperature operation up to 125°C to withstand harsh operating environments. The photocoupler trio also supports 200 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.

The company’s expanded portfolio of small isolation devices offers users greater layout flexibility with more options to enable longer secured creepage distance for high-voltage inverter control applications.
