Overview
The ISP827BLG is a high-density, dual-channel phototransistor optically coupled isolator manufactured by Isocom Components. It features a plastic DIP-8 package and provides a minimum isolation voltage of 5300 Vrms. The device includes two independent channels with separate configurations. Key electrical specifications include a maximum collector-emitter breakdown voltage of 35 V, a nominal current transfer ratio of 200%, and a maximum dark power supply current of 100 nA. It supports a maximum forward current of 0.05 A and operates within a temperature range of -55 °C to 100 °C.
Feature Summary
- Dual-channel configuration for independent signal isolation
- High insulation voltage capability for robust noise immunity
- Compliant with UL recognition and VDE approval standards
Applications
- Logic-to-logic isolation in noisy environments
- Line receiver circuits
- Programmable current level sensors
- Digital control of motors and servo machines
- Computer and peripheral device interfaces
Procurement Notes
Verify the specific suffix 'BLG' against official Isocom documentation to confirm lead form and packaging details. Ensure compliance requirements such as UL File No. E91231 and VDE 0884 are explicitly stated for this variant. Confirm RoHS status and lead-free certification prior to procurement to meet regulatory standards.
Selection Notes
Select this component when dual-channel isolation is required within a standard DIP-8 footprint. Consider the 5300 V isolation rating for applications demanding high dielectric strength. Verify that the 35 V collector-emitter breakdown voltage and 200% CTR meet the specific circuit design requirements for load driving capabilities.
Part Context
This part belongs to the ISP817/ISP827/ISP847 series of high-density mounting phototransistor optically coupled isolators from Isocom Components. The series is designed as an industry-standard alternative for legacy components, offering reliable performance in commercial and industrial applications requiring galvanic isolation.
Replacement Considerations
Isocom positions its products as direct replacements for industry-standard optocouplers. Potential equivalents may include models from other manufacturers offering similar pinouts and electrical characteristics, though specific cross-references should be validated against official substitution guides.
