PS2502-2G

Overview

The PS2502-2G is a dual-channel optocoupler from the PS2502 series, manufactured by Isocom Components. It features a Darlington transistor output configuration with high current transfer capability. The device provides robust electrical isolation between input and output circuits. Key specifications include a maximum isolation voltage of 5000Vrms and a typical current transfer ratio of 200%. It operates within a temperature range of -30°C to 100°C and is housed in an 8-pin DIP package suitable for through-hole mounting.

Feature Summary

• Dual-channel architecture providing independent signal isolation paths
• Darlington transistor output stage for high gain and drive capability
• High isolation voltage rating ensuring safety in high-voltage applications
• Wide operating temperature range for industrial environment reliability

Applications

• Industrial automation control systems
• Power supply feedback loops
• Microcontroller interface isolation
• Motor drive circuit protection

Procurement Notes

Verify the specific suffix 'G' against official manufacturer documentation to confirm RoHS compliance status and exact pinout compatibility. Ensure the sourcing channel provides valid traceability certificates. Cross-reference the part number with the latest datasheet revision to confirm no design changes have occurred that affect form, fit, or function parameters.

Selection Notes

Select this component when high current transfer ratio is required for driving loads directly without additional amplification. The dual-channel configuration allows for cost-effective isolation of multiple signals in compact spaces. Consider the thermal management requirements due to the Darlington output structure's higher saturation voltage compared to single transistors.

Part Context

This part belongs to the PS2502 series of optocouplers, which are designed for general-purpose isolation applications. The series typically offers variants with different packaging options and output configurations. The PS2502-2G specifically denotes the dual-channel version with Darlington outputs, distinguishing it from single-channel or phototransistor output variants in the same family.

Replacement Considerations

Direct replacements may include other dual-channel Darlington optocouplers with similar 5000Vrms isolation ratings. Verify pin compatibility and current transfer ratio specifications before substitution. Check for equivalent package dimensions to ensure mechanical fit on existing PCB layouts.
