PS2505-2-A

Overview

The CEL PS2505-2-A is a dual-channel transistor output optoisolator housed in an 8-DIP package. It provides 5000Vrms isolation voltage and supports AC or DC input signals. The device features a typical forward voltage of 1.17V with a maximum DC forward current of 80mA. Output specifications include a maximum collector-emitter voltage of 80V, a channel current capacity of 50mA, and a maximum saturation voltage of 300mV. The Current Transfer Ratio ranges from 80% to 600% at 5mA input. Typical rise and fall times are 3µs and 5µs respectively. It operates within a temperature range of -55°C to 100°C.

Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• High insulation voltage rating for safety separation
• Compatible with both AC and DC input signal types
• Low saturation voltage for efficient switching

Applications

• Industrial control systems requiring galvanic isolation
• Solid-state relay driver circuits
• Microcontroller interface isolation
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'A' against the manufacturer datasheet to confirm pinout and electrical tolerances. Confirm package dimensions match the 8-DIP (0.300 inch) specification. Check component status as this part may be obsolete or restricted. Ensure environmental compliance requirements align with REACH standards before procurement.

Selection Notes

Select this component when dual-channel isolation is required within an 8-pin DIP footprint. Verify that the 80V output voltage rating meets circuit demands. Ensure the 50mA output current capability is sufficient for the load. Confirm compatibility with the system's operating temperature range of -55°C to 100°C.

Part Context

This component belongs to the NEPOC series of optoisolators manufactured by CEL. It is part of a family including single, dual, and quad channel variants with similar electrical characteristics but different pin counts. The PS2505-2-A specifically addresses applications needing two isolated channels in a standard through-hole package.

Replacement Considerations

Consult official substitution guides for equivalent parts. Verify pin compatibility and electrical parameters such as CTR and isolation voltage. Ensure replacement components meet the same package and thermal requirements.
