Renesas Creepage Photocouplers

Renesas RV1S92 and RV1S22 series photocouplers offer 8.2mm of creepage in a narrow and thin package, enabling a PCB area reduction and higher design density in smart factories and solar inverters while meeting the creepage and clearance requirements of new safety standards.

The RV1S92 and RV1S22 series are the smallest 8.2mm creepage photocouplers available, offered in an LSSO5 package with a 0.65mm pitch or an LSSOP package with a 1.3mm pitch.  Compared to the conventional LSO5 package, the 2.5mm width of the LSSO5 and LSSOP reduces PCB area by 35%.

The packages are also very low profile, with a height of just 2.1mm, which allows designers to place the photocouplers on the bottom of the PCB for additional space-savings and greater flexibility in placing topside components. Variants include support for 15Mbps communications, an IPM driver, and transistor output from a DC, low current DC, or AC input.

The photocouplers are designed for harsh environments of factories and solar farms and provide improved safety over digital isolators. The internal structure of the RV1S92 and RV1S22 photocouplers ensures 150µm insulation distance, compared to 10µm for digital isolators. 

It also ensures the photocoupler will fail open, while digital isolators fail closed. The photocouplers provide 5000Vrms reinforced isolation to support 200V and 400V systems with reinforced insulation. 

They can tolerate 50kV/µs common-mode transients, operate at temperatures up to 125°C, and they meet UL61800-5-1 for motor drives and UL61010-2-201 for PLCs and other control devices.
