PS2505-2XSM

Overview

The PS2505-2XSM is a surface-mount optically coupled isolator from the PS2505 series by Isocom Components. It features two infrared light-emitting diodes connected in inverse parallel for AC or polarity-insensitive input, paired with NPN silicon phototransistors. The device provides high isolation voltage of 5300Vrms and 7500Vpk. It is housed in an 8-pin SOP package with a 10mm lead spread option available via suffix 'G'. All electrical parameters are 100% tested.

Feature Summary

• AC input capability due to inverse parallel LED configuration
• High isolation voltage rating for safety
• Surface mount packaging for automated assembly

Applications

• Computer terminals
• Industrial system controllers
• Signal transmission between systems of different potentials

Procurement Notes

Verify the specific suffix requirements against the official datasheet to ensure correct package type and tape-and-reel availability. Confirm that the 'SM' designation aligns with the required surface mount footprint and lead pitch specifications for your PCB design before finalizing procurement orders.

Selection Notes

Select this component when AC input detection or polarity-insensitive operation is required in a compact surface-mount form factor. Ensure the circuit design accommodates the inverse parallel LED structure and verify that the 5300Vrms isolation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the PS2505 series, which includes variants like PS2505-1, PS2505-2, and PS2505-4. The series is characterized by high-density packaging and robust isolation capabilities, serving as a replacement for standard optocouplers in space-constrained industrial and commercial electronics.

Replacement Considerations

Check for direct equivalents such as NEC PS2505-2-X or similar high-isolation AC-input phototransistor optocouplers in SOP-8 packages. Verify pinout compatibility and electrical parameter overlaps before substitution.
