Overview
The ISP817XDG is a single-channel optocoupler from Isocom Components, housed in a 4-pin PDIP package. It integrates an infrared LED with an NPN silicon phototransistor output. Key electrical parameters include a maximum forward voltage of 1.65V and a peak input current of 60mA. The device offers a high isolation voltage of 5300Vrms (7500V pk). Typical switching characteristics feature a rise time of 2µs and a fall time of 11µs. The current transfer ratio ranges from 40% to 80%, supporting DC input applications.
Feature Summary
- Integrates an infrared emitting diode with an NPN silicon phototransistor for signal isolation
- Provides high-voltage electrical isolation between input and output circuits
- Designed for high-density mounting in standard through-hole configurations
Applications
- Signal isolation in digital communication interfaces
- Switching power supply feedback loops
- Microcontroller input/output isolation
Procurement Notes
Verify the specific suffix 'DG' against official manufacturer documentation to confirm exact packaging or tape-and-reel specifications. Ensure the component meets required safety certifications such as UL for the intended application environment. Cross-reference pinout diagrams with system design requirements to prevent installation errors.
Selection Notes
Select this component when a single-channel isolation barrier is required with moderate speed performance. The 5300Vrms rating suits general industrial isolation needs. Verify that the 40-80% current transfer ratio aligns with the load driving capabilities of the target circuit design.
Part Context
Isocom Components specializes in infrared optoelectronic devices. The ISP series represents their line of high-density optocouplers. This model belongs to the broader family of transistor-output isolators designed for reliable signal transmission across isolated boundaries.
Replacement Considerations
Direct substitutes may include other CNY17-series variants or equivalent 4-pin DIP optocouplers with matching isolation ratings and pinouts. Verify functional equivalence before substitution.
