- Provides high isolation voltage for safety
- Features high current transfer ratio
- Available in surface mount or tape & reel options
Applications
- Computer terminals
- Industrial systems controllers
- Measuring instruments
- Signal transmission between systems of different potentials and impedances
Procurement Notes
Verify the specific suffix 'G' indicates the 10mm lead spread option as documented in official Isocom datasheets. Confirm RoHS compliance status and UL/VDE recognition numbers directly from the manufacturer's certification documents before procurement. Ensure the selected packaging variant matches the required assembly process, whether standard through-hole or surface mount tape and reel.
Selection Notes
Select this component when high current transfer ratio and robust isolation are required for interfacing low-power control signals with higher load requirements. The photodarlington output offers greater sensitivity compared to standard phototransistors. Consider the physical package dimensions and lead form compatibility with the target PCB layout during the design phase.
Part Context
This part belongs to the ISP815/ISP825/ISP845 series of high-density mounting photodarlington optically coupled isolators. The series is designed for applications requiring compact solutions with high reliability. The 'G' suffix typically denotes a specific lead configuration variation within the product family, distinct from standard or surface mount variants.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with other photodarlington optocouplers requires careful verification of pinout compatibility, isolation voltage ratings, and current transfer ratio specifications against the original design requirements.
