Overview
The ISP827CG is a dual-channel optocoupler manufactured by Isocom Components 2004 LTD. It features surface mount packaging with eight pins and provides electrical isolation of 5300 Vrms between input and output circuits. The device supports a maximum forward current of 50 mA and offers a minimum current transfer ratio of 200% at 5 mA. Designed for high-density applications, it integrates infrared LEDs with NPN phototransistors to ensure reliable signal transmission in isolated environments.
Feature Summary
- Dual-channel configuration for simultaneous signal isolation
- High voltage isolation capability of 5300 Vrms
- Surface mount package design for automated assembly
- NPN phototransistor output for digital switching
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in microprocessor-based circuits
- Power supply feedback loops
- Data communication interface isolation
Procurement Notes
Verify the specific suffix CG against official Isocom documentation to confirm pinout and packaging variations. Ensure compatibility with existing PCB footprints before integration. Cross-reference datasheet parameters such as current transfer ratio and isolation voltage with system requirements. Confirm availability through authorized distributors only to prevent counterfeit components.
Selection Notes
Select this component when dual-channel isolation is required in a compact surface mount form factor. Consider the 5300 Vrms rating for high-noise industrial environments. Evaluate the 200% minimum CTR for logic-level interfacing needs. Compare rise and fall times against signal speed requirements to ensure adequate performance for the intended application bandwidth.
Part Context
The ISP827 series belongs to Isocom's range of high-performance infrared optoelectronic devices. These components are designed as industry-standard replacements for common commercial optocouplers. The manufacturer specializes in providing flexible manufacturing options and various lead forms to meet specific customer circuit design requirements.
Replacement Considerations
Official substitutes include other models within the ISP827 family or equivalent dual-channel optocouplers from other manufacturers that match the 5300 Vrms isolation and 8-pin SMD package specifications.
