• Provides electrical isolation with high noise immunity of 20 kV/µs common mode transient immunity.
• Achieves low input voltage operation and low power consumption suitable for space-constrained applications.

Applications

• Motor control systems
• Programmable Logic Controller (PLC) interfaces
• Industrial equipment signal transmission

Procurement Notes

Verify component status as NRND (Not Recommended for New Designs). Confirm datasheet version and ECAD model availability before integration. Check moisture sensitivity levels and reflow soldering profiles. Ensure supply chain stability due to end-of-life designation. Validate replacement options if long-term production is required.

Selection Notes

Select this component for applications requiring high-speed digital isolation with compact footprint. Consider the 20 Mbps data rate and 3750 Vrms isolation barrier. Evaluate thermal performance within the -40°C to +105°C operating range. Assess compatibility with TTL logic outputs and 3-5V DC supply requirements.

Part Context

Part of the APS1/APS2 PhotoIC Coupler series by Panasonic Industry. These devices combine LED and receiver ICs on a single chip for efficient signal transmission. The series is designed for industrial automation, offering robust isolation and fast switching speeds compared to standard optocouplers.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative sourcing or redesign may be necessary for new projects.
