ISP847XG

Transistor, Photovoltaic Output Optoisolators Overview

The ISP847XG is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. It features four separate channels within a single DIP-16 plastic package, providing robust electrical isolation for multi-channel signal transmission. The device utilizes an NPN phototransistor output configuration and supports a maximum forward current of 50 mA per channel. It offers a nominal current transfer ratio of 200% and a minimum collector-emitter breakdown voltage of 35 V. The component is rated for a maximum insulation voltage of 5300 Vrms and operates within a temperature range of -55 °C to 100 °C.

• Four independent channels integrated into a single high-density DIP-16 package for space-efficient circuit design.
• Provides high-voltage electrical isolation with a rated insulation voltage of 5300 Vrms between input and output circuits.
• Features NPN phototransistor outputs suitable for digital switching and logic interface applications.

Transistor, Photovoltaic Output Optoisolators Applications

• Multi-channel industrial control systems requiring galvanic isolation
• Data acquisition modules needing isolated signal inputs
• Power supply monitoring circuits with multiple feedback paths

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'XG' against official Isocom documentation to confirm lead frame plating and packaging specifications. Ensure the required current transfer ratio matches the 200% nominal value for your application. Confirm compliance with UL and VDE standards if safety certification is mandatory for the end product. Check that the DIP-16 footprint aligns with the target PCB layout constraints.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when four isolated channels are required in a compact form factor. The 5300 Vrms isolation rating makes it suitable for high-noise environments or mains-connected equipment. Consider the 200% CTR for driving standard logic loads without excessive input current. Verify that the 100 °C maximum operating temperature meets the thermal requirements of the installation environment.

Transistor, Photovoltaic Output Optoisolators Part Context

The ISP847XG belongs to the ISP817/ISP827/ISP847 series of high-density mounting phototransistor optically coupled isolators. This series is designed to replace legacy components while offering improved packing density. The 'XG' designation typically indicates specific manufacturing attributes such as lead form or RoHS compliance, distinct from the base part number which defines the electrical characteristics.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements include other quad-channel optocouplers in DIP-16 packages with similar isolation ratings. Verify pinout compatibility before substitution. Generic equivalents may differ in current transfer ratio or propagation delay. Consult manufacturer cross-reference lists for confirmed compatible parts.
