ISP321-4G

Transistor, Photovoltaic Output Optoisolators Overview

The ISP321-4G is a quad-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a 16-pin DIP package and utilizes infrared LEDs coupled with NPN silicon phototransistors. The device provides an isolation voltage of 5300Vrms and supports a collector-emitter voltage (Uce) of 80V. Key electrical characteristics include a rise time of 4μs and a fall time of 3μs, ensuring rapid response capabilities for signal transmission.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Quad-channel configuration integrating four independent isolation circuits within a single 16-pin package
• High dielectric strength providing robust electrical isolation between input and output sides
• Fast switching performance with specified nanosecond-scale rise and fall times

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring multi-channel signal isolation
• Data communication interfaces needing high-voltage protection
• Microprocessor-based systems for noise immunity enhancement

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'G' against official Isocom documentation to confirm lead-free compliance or RoHS status, as suffixes often denote material variations. Ensure the 16-DIP package type matches the target PCB footprint requirements. Cross-reference the 5300Vrms rating with system insulation standards before finalizing component selection.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required in a compact form factor. The 80V collector-emitter voltage suits low-voltage logic interfacing. Consider the 4μs/3μs timing parameters for applications demanding moderate-speed digital signal transfer without significant propagation delay penalties.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISP321 series of high-density optically coupled isolators. It shares architectural similarities with models like ISP321-4XSM but differs in packaging and specific mechanical dimensions. The series is designed to replace legacy components while offering improved parameter consistency and manufacturing reliability under global industry standards.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include ISP321-4XSM and ISP321-4GBG from the same manufacturer family. Verify pin compatibility and thermal characteristics when swapping between DIP and surface-mount variants.
