RV1S92xxA IC Photocouplers Renesas Electronics RV1S92xxA Photocouplers use tiny LSSO5 packages with a 0.65mm pin pitch. These compact devices secure creepage distance to 8.2mm and reduce the mounting area by 35% in comparison with a conventional LSO5 package. With a package height of 2.1mm, these photocouplers can be directly mounted on the backside of a PCB, freeing up valuable space for topside mounted components. Three times infrared reflow soldering provides maximum flexibility. The RV1S92xxA Photocouplers' electric isolation and high CMR noise rejection (50kV/µs) protects low voltage microcontrollers and I/O devices from high voltage circuits when transferring high-speed signals.
