ISP827X-3

Transistor, Photovoltaic Output Optoisolators Overview

The ISP827X-3 is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. It features a dual-channel configuration within a plastic DIP-8 package, providing 5300 Vrms isolation voltage between input and output circuits. The device utilizes a gallium arsenide infrared LED paired with a silicon phototransistor for signal transmission. 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%. It operates within a temperature range of -55°C to +100°C and meets UL and VDE safety standards.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel optical isolation architecture
• High insulation voltage rating
• Compliant with international safety approvals

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Signal interface in noisy electrical environments
• Power supply feedback loops

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific lead form suffix associated with the 'X' designation, as the manufacturer offers STD, G, and other forms. Confirm that the required safety certifications (UL File No. E91231 and VDE 0884) are explicitly documented for the exact part variant being procured. Ensure the plastic DIP-8 package type matches the board layout requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a compact footprint. The 5300 Vrms isolation capability suits high-voltage separation needs. Consider the 200% CTR for driving standard logic inputs. Verify thermal management capabilities given the 100°C maximum operating temperature limit.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISP817/ISP827/ISP847 series of high-density phototransistor optocouplers. The 'X' suffix indicates specific approval specifications including UL recognition and VDE compliance. It is distinct from single-channel or quad-channel variants in the same family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes must match the 5300 Vrms isolation, DIP-8 package, and dual-channel configuration. Verify equivalent CTR and breakdown voltage ratings. Cross-reference UL and VDE file numbers for compatibility.
