As an extension to earlier R2Coupler models ACPL-KxxT, the new devices feature two optocoupler channels that are adjusted internally at an angle of 180 degrees. Thus they offer the best pin assignment for PCB layouts in bidirectional Tx/Rx data exchange circuits. In addition, both channels are completely decoupled and galvanically insulated, offering an ideal bidirectional communications interface for power systems. What’s more, the systems also feature a clearance and creepage distance of 8 mm, a high dielectric breakdown voltage (VISO) up to 5.000 VRMS for at least 1 minute as well as a high constant operating voltage up to 1.140 VPEAK. The coptocouplers come in a compact SSO-12 package which offers comparable dimensions as the SSO-8 package of earlier component generations.
With an operating temperature range from -40°C to +125°C the optocouplers are ideal for deployment in the engine compartment; the application voltage of 1000V makes them suitable for electric powertrain applications.
