Overview
The PS2505-4X is a high-density, four-channel optically coupled isolator manufactured by Isocom Components. It features an AC input configuration utilizing two infrared LEDs connected in inverse parallel per channel, paired with NPN silicon phototransistor outputs. The device provides 5300Vrms isolation voltage and operates within a temperature range of -30°C to 100°C. Key electrical parameters include a maximum forward voltage of 1.4V, typical rise/fall times of 4μs/3μs, and a minimum current transfer ratio of 80%. Packaged in a 16-pin DIP for through-hole mounting, it supports a maximum input current of 50mA.
Feature Summary
- AC or polarity insensitive input design using inverse parallel infrared LEDs
- High isolation voltage capability of 5300Vrms for robust signal transmission between systems of different potentials
- Four-channel density in a space-efficient dual in-line plastic package
Applications
- Computer terminals
- Industrial system controllers
- Telephone sets and exchanges
- Signal transmission between systems of different potentials and impedances
Procurement Notes
Verify the specific suffix 'X' against official manufacturer documentation to confirm exact packaging or testing variations. Ensure compatibility with existing PCB footprints for 16-pin DIP configurations. Confirm that the AC input requirement aligns with the circuit design, as this component does not require polarity matching for the input side.
Selection Notes
Select this component when high-density isolation is required for AC-coupled signals. The inverse parallel LED structure eliminates the need for external rectification circuits on the input side. Consider the 5300Vrms isolation rating for applications demanding significant potential difference separation between control and load sides.
Part Context
The PS2505 series belongs to Isocom's high-density phototransistor optocoupler family. These devices are designed as industry-standard replacements for legacy multi-channel isolators. The series offers customizable electrical parameters to meet specific circuit design requirements while maintaining compliance with global safety standards such as UL and VDE.
Replacement Considerations
Publicly confirmed substitute part numbers include PS2505-4 from NEC and California Eastern Labs. Verify pinout compatibility and electrical parameter tolerances before substitution.
