ISP817XGRG

Overview

The ISP817XGRG is a single-channel optocoupler from the ISP series, manufactured by Isocom Components. It features an NPN phototransistor output and accepts DC input current with a maximum rating of 50 mA. The device provides high isolation voltage of 5300 Vrms and operates within a temperature range of -30°C to +100°C. Typical switching times are 4 µs for rise and 3 µs for fall. The component is housed in a surface-mount DIP package.

Feature Summary

• Single-channel optical isolation with NPN phototransistor output
• High dielectric strength providing robust circuit separation
• Surface-mount packaging for automated assembly integration

Applications

• Signal isolation in industrial control systems
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix GRG against official datasheets to confirm surface-mount configuration and tape-and-reel packaging details. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference manufacturer part numbers to avoid substitution errors with through-hole variants.

Selection Notes

Select this component when surface-mount technology is required for single-channel isolation. Compare current transfer ratio specifications against load requirements. Verify that the 5300 Vrms isolation rating meets safety standards for the target application environment.

Part Context

This part belongs to the ISP series of infrared optoelectronic devices. Isocom Components specializes in replacing discontinued industry-standard optocouplers with equivalent or improved performance alternatives. The series offers various pin configurations and output types to support diverse electronic design needs.

Replacement Considerations

Check for direct equivalents such as CNY17F-1XG for through-hole applications if layout changes are permissible. Verify pinout compatibility before substituting with other single-channel transistor output optocouplers.
