New Family of 15 Mbps Photocouplers for Harsh Industrial Applications

Renesas Electronics Corporation released three new 15 Mbps photocouplers designed to withstand the harsh operating environments of industrial and factory automation equipment. The photocouplers will fulfil the need of smaller ICs with lower power consumption in higher voltage and compact systems. The RV1S9x60A photocoupler family comes in best-in-class low threshold input current (IFHL) ratings where the RV1S9160A (SO5) operates at 2.0mA, the RV1S9060A (LSO5) at 2.2mA, and the RV1S9960A (LSDIP8) at 3.8mA. The devices are an ideal solutions for applications such DC to AC power inverters, AC servo motors, programmable logic controllers (PLCs), robotic arms, solar and wind input power conditioners, and battery management systems for energy storage and charging.

 

The RV1S9x60A photocoupler family features lower power consumption which allows it to suppress power supply heat generation whereas high temperature operation up to 125°C enables board space savings by mounting the photocoupler near the IGBT or MOSFET power device. The common mode rejection ration up to 50 kV/µs (min) of photocoupler protect microcontrollers and other I/O logic circuits from high voltage spikes while transferring high-speed signals. Also, the devices comes in 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.

 

Key Features of RV1S9160A, RV1S9060A and RV1S9960A Photocouplers:

  • Low voltage power supply operation of 2.7V to 5.5V
  • Isolation voltage: 3750 Vrms (RV1S9160A), 5000 Vrms (RV1S9060A), and 7500 Vrms (RV1S9960A)
  • High temperature operation from -40°C to +125°C (RV1S9160A and RV1S9060A), and from -40°C to +110°C (RV1S9960A)
  • Supply current of 2.0mA max
  • Low pulse width distortion at 20ns max
  • Propagation delay of 60ns max; and propagation delay skew of 25ns max

 

The samples and production quantities of RV1S9x60A 15Mbps photocouplers are available now directly from Authorised Distributors of Renesas. The devices comes in different package and pricing listed below:
