Overview
The ISP824G is a dual-channel optocoupler manufactured by Isocom Components 2004 LTD. It features an AC input configuration and transistor output type. The device provides high isolation voltage of 5300Vrms between input and output channels. It is housed in an 8-DIP package with a pin spacing of 0.400 inches (10.16mm). The unit supports a collector current of 50 mA and offers a typical isolation capacitance of 20%. This component is designed for applications requiring reliable electrical isolation in compact form factors.
Feature Summary
- Dual channel architecture for independent signal isolation
- AC input capability for direct alternating current drive
- High voltage isolation rating for safety-critical circuits
- Transistor output stage for digital switching applications
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops for voltage regulation
- Microcontroller interface circuits for noise immunity
- Solid-state relay driver stages
Procurement Notes
Verify the specific suffix designation to confirm package style, as variations exist between DIP and SMD formats. Ensure the procurement documentation explicitly references the 5300Vrms isolation rating and 8-pin configuration. Cross-reference the manufacturer part number against official Isocom Components databases to avoid counterfeit or obsolete stock. Confirm lead times and authenticity through authorized distribution channels only.
Selection Notes
Select this component when dual-channel isolation is required within a standard DIP footprint. The AC input feature simplifies circuit design for alternating current signals without additional rectification. Consider the 5300Vrms isolation level for high-voltage separation requirements. Evaluate the 50 mA output current capacity against load demands. Compare physical dimensions against PCB layout constraints before finalizing the design.
Part Context
The ISP824G belongs to the ISP824 series of optocouplers from Isocom Components 2004 LTD. This series includes variants such as ISP824XSMT&R in surface mount packages. The family focuses on providing robust isolation solutions for industrial and commercial electronics. The dual-channel design allows for cost-effective implementation of multi-isolated interfaces in space-constrained applications.
Replacement Considerations
Direct substitutes include other dual-channel optocouplers with comparable 5300Vrms isolation and 8-DIP packaging. Verify pin compatibility and electrical characteristics such as CTR and propagation delay. Alternative manufacturers may offer similar specifications but require thorough validation of mechanical fit and performance margins.
