Overview
The ISP825-1G is a dual-channel optoisolator manufactured by Isocom Components 2004 LTD. It features an 8-DIP package and utilizes a Darlington transistor output configuration. The device provides a high isolation voltage of 5300Vrms between input and output channels. Designed for through-hole mounting, it supports AC input signals and operates within a temperature range of -30°C to 100°C. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 4μs, and a typical fall time of 3μs. The component carries UL standard certification.
Feature Summary
- Dual-channel architecture providing independent signal isolation paths within a single package
- Darlington output stage designed for high current transfer ratio applications
- High dielectric isolation capability suitable for demanding industrial environments
- AC input compatibility allowing direct coupling with alternating current sources
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops for safety compliance
- Communication interface isolation in noisy environments
Procurement Notes
Verify the specific suffix '1G' against official Isocom documentation to confirm pinout and insulation class requirements. Ensure the procurement channel provides valid UL certification records. Confirm that the 8-DIP package dimensions match the target PCB layout constraints before finalizing orders.
Selection Notes
Select this component when dual-channel isolation is required within a standard DIP footprint. The Darlington output offers higher gain compared to standard transistor outputs, making it suitable for driving loads directly. Consider the 5300Vrms isolation rating for applications involving high potential differences between circuits.
Part Context
Isocom Components 2004 LTD specializes in infrared optoelectronic devices with over 40 years of industry expertise. The company traces its origins to Litronix management acquired by Siemens in 1982. Established as an independent brand in 1984, Isocom focuses on reliable optocoupler solutions for commercial and industrial markets.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify pin compatibility and isolation ratings with alternative manufacturers if substitution is necessary.
