PS2502-4XSMT&R

Overview

The PS2502-4XSMT&R is a surface-mount, four-channel optocoupler manufactured by Isocom Components. It features Darlington transistor outputs for high current transfer efficiency and provides electrical isolation between input and output circuits. The device utilizes an infrared LED coupled to photodetectors within a compact SMD package. Key specifications include a maximum forward voltage of 1.6V, a typical rise time of 3µs, and a typical fall time of 3µs. It supports a maximum input current of 50mA and offers a minimum isolation voltage of 5000Vrms. The unit operates within a temperature range of -30°C to 100°C.

Feature Summary

• Four independent channels provide multi-circuit isolation in a single component.
• Darlington transistor outputs deliver high current transfer ratios for sensitive load driving.
• High isolation voltage ensures robust safety barriers between control and power sides.
• Surface-mount packaging facilitates automated assembly and space-constrained designs.

Applications

• Industrial automation control systems
• Power supply unit feedback loops
• Multi-channel signal isolation interfaces
• Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix 'XSMT&R' against official manufacturer documentation to confirm surface-mount tape-and-reel availability and pinout configuration. Ensure that the Darlington output characteristics align with the target application's switching speed requirements, as these devices typically exhibit slower response times compared to standard transistor outputs. Confirm compliance with relevant safety standards such as UL recognition before final integration.

Selection Notes

Select this component when multiple isolated channels are required within a limited board area. The Darlington output architecture is suitable for applications demanding high current gain rather than high-speed switching. Evaluate the thermal management capabilities of the PCB layout, as multiple active channels can generate heat. Compare the isolation voltage rating against the system's transient surge requirements to ensure adequate safety margins.
