PS2501-4XGRSMT&R

Overview

The PS2501-4XGRSMT&R is a surface mount optocoupler from Isocom Components, featuring four channels in a 16-pin SMD package. It utilizes a phototransistor output configuration with an LED input. Key electrical parameters include a maximum forward voltage of 1.4V, a peak forward current of 50mA, and a high isolation voltage of 5300Vrms. The device operates within a temperature range of -30°C to 100°C, offering typical rise and fall times of 4μs and 3μs respectively, ensuring reliable signal transmission in isolated circuits.

Feature Summary

• Four-channel optical isolation for multi-signal processing
• High dielectric strength between input and output sides
• Surface mount design for automated assembly integration

Applications

• Industrial control systems requiring signal isolation
• Power supply units needing feedback loop separation
• Communication equipment interface protection

Procurement Notes

Verify the specific suffix 'GRSMT&R' against official Isocom documentation to confirm tape-and-reel packaging and grade specifications. Ensure compatibility with standard reflow soldering profiles for surface mount technology. Cross-reference pinout diagrams with the manufacturer's datasheet to prevent orientation errors during PCB assembly. Confirm that the 16-pin SOP/DIP-SMD footprint matches your board layout requirements precisely.

Selection Notes

Select this component when multiple isolated channels are required in a compact surface mount form factor. The 5300Vrms isolation rating suits applications demanding robust safety barriers. Consider the 80% minimum CTR for driving logic inputs directly. Evaluate thermal management needs given the 100°C maximum operating temperature limit. Compare channel density against through-hole alternatives if space constraints are critical.

Part Context

This part belongs to the PS2501 series of high-density mounting phototransistor optically coupled isolators. Isocom Components manufactures these devices to replace obsolete or hard-to-find optocouplers. The series is designed for general-purpose isolation in various electronic circuits, offering reliability and performance comparable to industry standards.

Replacement Considerations

Check for direct equivalents like PS2501-4XSM or PS2501-4GRSM from the same manufacturer. Verify pin compatibility and electrical characteristics before substituting with parts from other vendors. Ensure any replacement maintains the required isolation voltage and channel count.
