ISP321-2XGB

Transistor, Photovoltaic Output Optoisolators Overview

The ISP321-2XGB is a dual-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a transistor output configuration housed in an 8-DIP package. The device provides an isolation voltage of 5300Vrms between input and output circuits. Key electrical specifications include a maximum forward current of 50 mA, a collector-emitter breakdown voltage of 80 V, and a minimum current transfer ratio (CTR) of 50%. This component is designed for applications requiring reliable signal isolation with high voltage withstand capabilities.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel architecture providing independent signal isolation paths within a single package

• Transistor output stage suitable for interfacing with digital logic and control systems

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Power supply units for feedback loop isolation
• Smart metering infrastructure for safe data transmission

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'GB' against the manufacturer's official datasheet to confirm pinout compatibility and packaging dimensions. Ensure that the required Current Transfer Ratio (CTR) bin matches your circuit design constraints, as Isocom often offers multiple CTR grades for the same base part number. Confirm lead times directly with authorized distributors as availability varies.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required in a compact DIP footprint. The 5300Vrms rating supports high-noise industrial environments. Compare the 50% minimum CTR against system gain requirements. Consider surface-mount alternatives like the ISP321-2XGBSMT&R if PCB space is limited, noting that package type changes do not alter internal functionality.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISP321 series from Isocom Components, which specializes in infrared optoelectronic devices. The series includes single, dual, and quad channel variants with different output types. Isocom positions these components as industry-standard replacements, offering flexible manufacturing options and specialized parameter selection for custom circuit designs.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other dual-channel transistor-output optocouplers with similar 5300Vrms isolation and 8-pin DIP packages. Verify pin-to-pin compatibility before substitution. Surface-mount equivalents such as the ISP321-2XGBSMT&R offer identical electrical performance in a different form factor.
