Overview
The ISP827-1G is a dual-channel transistor output optocoupler manufactured by Isocom Components. It features a plastic DIP-8 package and provides 5300 V isolation voltage between input and output circuits. The device operates within a temperature range of -55 °C to +100 °C. Key electrical parameters include a minimum collector-emitter breakdown voltage of 35 V, a maximum forward current of 50 mA, and a nominal current transfer ratio of 200%. The component is lead-free, RoHS compliant, and holds UL and VDE approvals for safety standards.
Feature Summary
- Provides high-density mounting with 5300 V isolation capability for safe signal transmission across isolated grounds.
- Features dual independent channels in a compact DIP-8 plastic package for space-constrained designs.
- Includes UV recognition and VDE approval for compliance with international safety regulations.
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal interfacing between microcontrollers and high-voltage circuits
Procurement Notes
Verify the specific suffix '1G' against the manufacturer's official datasheet to confirm pinout configuration and lead form variations. Ensure that the required isolation voltage rating of 5300 V aligns with the system's safety clearance requirements. Confirm RoHS and UL/VDE certification status if regulatory compliance is mandatory for the end application.
Selection Notes
Select this component when high isolation voltage and dual-channel functionality are required in a standard DIP package. Consider the 200% nominal CTR for driving sensitive loads. Evaluate the -55 °C to +100 °C operating range against environmental conditions. Compare against alternative optocouplers if lower isolation ratings or single-channel configurations suffice.
Part Context
The ISP827 series belongs to Isocom Components' line of high-density phototransistor optically coupled isolators. These devices utilize a transistor output configuration suitable for general-purpose switching applications. The series is designed to replace older optocoupler technologies while maintaining compatibility with standard DIP footprints.
Replacement Considerations
Check for direct cross-references from manufacturers like Vishay or Broadcom offering identical 5300 V isolation and DIP-8 packaging. Verify pin-to-pin compatibility before substitution.
