Overview
The PS8821-2-F3-AX is a high-speed analog output optocoupler manufactured by Renesas Electronics Corporation. It features dual-channel transistor outputs with 2500Vrms isolation voltage and supports data rates up to 1 Mbps. The device operates with an input forward current of 16 mA at the specified Current Transfer Ratio (CTR) point, providing an output current capability of 8 mA. The CTR range is documented between 20% and 20%. It is available in a lead-free SSOP-8 package compliant with RoHS standards.
Feature Summary
- Provides galvanic isolation with a breakdown voltage of 2.5 kV rms
- Supports high-speed data transmission up to 1 Mbps
- Features dual-channel linear output configuration for precise signal transfer
Applications
- Industrial control systems requiring signal isolation
- Power management circuits needing feedback isolation
- Communication interfaces demanding high-speed digital isolation
Procurement Notes
Verify the complete orderable part number PS8821-2-F3-AX against official Renesas documentation to ensure correct specification matching. Confirm compliance status for EU RoHS and China RoHS regulations as indicated by the specific suffix. Check datasheet revisions for any updates regarding pinout or electrical characteristics before integration into design schematics.
Selection Notes
Select this component when dual-channel isolation with high-speed analog output capabilities is required. Ensure the system voltage does not exceed the 2500Vrms isolation rating. Verify that the required current transfer ratio falls within the documented 20% range at the specified 16 mA input current. Consider the SSOP-8 package constraints for PCB layout and thermal management during the selection process.
Part Context
This device belongs to the NEPOC series from Renesas, which focuses on optocouplers for industrial applications. It complements other models like the PS8802-2-V-F3-AX, offering similar isolation but with specific speed and output characteristics tailored for high-performance signal transmission needs in noisy environments.
Replacement Considerations
Check for direct substitutes such as the PS8821-2-V-F3-AX variant if different isolation voltage ratings are acceptable. Ensure any replacement maintains the 1 Mbps speed and dual-channel configuration. Verify package compatibility and electrical parameter alignment with the original specifications.
