Renesas Electronics has released three new 15 Mbps photocouplers designed to withstand the harsh operating environments of industrial and factory automation equipment.

The RV1S9x60A family offers best-in-class low threshold input current (IFHL) ratings: the RV1S9160A (SO5) operates at 2.0mA, the RV1S9060A (LSO5) at 2.2mA, and the RV1S9960A (LSDIP8) at 3.8mA. Lower power consumption allows the RV1S9x60A photocouplers to meaningfully suppress power supply heat generation. And high temperature operation up to 125°C enables board space savings by mounting the photocoupler near the IGBT or MOSFET power device. The photocouplers feature high common mode rejection (noise tolerance) up to 50 kV/µs (min) to protect microcontrollers and other I/O logic circuits from high voltage spikes while transferring high-speed signals. The RV1S9x60A family also offers a variety of packages with the smallest footprint for each reinforced isolation (up to 690 Vrms), and minimum creepage distances of 4.2mm to 14.5mm to ensure safe operation.
