PS2501-4XGRSM

Overview

The PS2501-4XGRSM is a surface-mount optocoupler from Isocom Components, featuring four channels in a 16-pin SOP package. It provides an isolation voltage of 5300Vrms and supports a maximum forward current of 50mA. The device exhibits a typical rise time of 4μs and fall time of 3μs, with a minimum current transfer ratio of 80%. Operating temperatures range from -30°C to 100°C.

Feature Summary

• Four-channel configuration for multi-signal isolation
• High isolation voltage rating for safety
• Surface-mount packaging for automated assembly

Applications

• Logic-to-logic isolation in noisy environments
• Line receiver circuits
• Programmable current level sensors
• Motor and servo machine digital control

Procurement Notes

Verify the specific suffix 'GRSM' against official manufacturer documentation to confirm exact pinout, lead finish, and tape-and-reel specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles before integration into production designs.

Selection Notes

Select this component when high-density four-channel isolation is required in a surface-mount form factor. Consider the 5300Vrms isolation rating for applications demanding robust electrical separation between input and output circuits.

Part Context

Isocom Components specializes in infrared optoelectronic devices and offers industry-standard replacements. The PS2501 series is designed for general-purpose isolation, providing reliable performance in commercial and industrial applications where space-saving surface-mount solutions are preferred.

Replacement Considerations

Cross-reference with equivalent four-channel DIP or SMD optocouplers such as the PC847 or IL300 variants if pin-compatible alternatives are needed. Verify that replacement parts meet the same isolation voltage and current transfer ratio requirements.
