PS2505-4XG

Overview

The PS2505-4XG is a four-channel optocoupler manufactured by Isocom Components. It features an AC input LED paired with a phototransistor output, providing electrical isolation rated at 5300Vrms. The device is housed in a 16-pin DIP package and supports a wide operating temperature range from -30°C to 100°C. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 4μs, and a typical fall time of 3μs. It complies with UL standards for safety.

Feature Summary

• Four-channel configuration for multi-signal isolation
• AC input capability for direct line interfacing
• High isolation voltage rating for safety compliance

Applications

• Industrial control systems
• Power supply protection circuits
• Smart metering applications

Procurement Notes

Verify the specific suffix 'XG' against official manufacturer documentation to confirm pinout and packaging variations. Ensure compatibility with existing PCB footprints and thermal management requirements before integration. Confirm regulatory certifications such as UL or VDE are applicable to this specific variant.

Selection Notes

Select this component when high-density isolation is required for AC-driven signals. The four-channel design reduces board space compared to single-channel alternatives. Verify that the AC input characteristics match the source circuitry and that the output current transfer ratio meets the load requirements.

Part Context

This part belongs to the PS2505 series of optocouplers produced by Isocom Components. The series is designed as a replacement for discontinued industry-standard components. Isocom specializes in infrared optoelectronic devices and provides flexible manufacturing options for commercial and industrial markets.

Replacement Considerations

Cross-reference with standard quad optocouplers featuring AC inputs. Verify pin compatibility and isolation ratings against legacy parts. Check datasheets for equivalent rise/fall times and CTR specifications.
