ISP847CG

Transistor, Photovoltaic Output Optoisolators Overview

The ISP847CG is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. It features four independent channels within a single DIP-16 plastic package, providing robust electrical isolation between input and output circuits. The device utilizes a transistor output configuration with NPN phototransistors. Key electrical specifications include a maximum insulation voltage of 5300 Vrms, ensuring safe operation in high-voltage environments. The collector-emitter breakdown voltage is specified at a minimum of 35 V, while the maximum forward current is rated at 50 mA. The nominal current transfer ratio for this variant is 200%, facilitating efficient signal transmission across the isolation barrier.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'CG' against official Isocom Components documentation to confirm the exact current transfer ratio and lead form variations. Ensure that the ordering information matches the required approval standards such as UL File No. E91231 and VDE 0884 certification. Cross-reference the datasheet revision date to confirm component availability and compliance status before procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select the ISP847CG when a quad-channel isolation solution is required in a standard DIP-16 footprint. Compare the 200% nominal CTR against other variants like the ISP847GBX (100% CTR) to ensure adequate drive capability for the load. Consider the operating temperature range of -55°C to 100°C for environmental suitability. Verify that the 5300 Vrms isolation voltage meets the system's safety clearance requirements.

Transistor, Photovoltaic Output Optoisolators Part Context

The ISP847CG belongs to the ISP847X series of high-density mounting phototransistor optically coupled isolators from Isocom Components. This series is designed for applications requiring multiple isolated channels in a compact package. The 'X' designation typically refers to specific lead form or packaging variations within the broader ISP847 family, which includes models like ISP817 and ISP827 with varying channel counts and performance characteristics.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other quad-channel optocouplers with similar DIP-16 packages and comparable isolation voltages. Verify compatibility with existing PCB footprints and thermal management requirements. Ensure replacement parts maintain equivalent UL and VDE approvals if regulatory compliance is critical.
