PS2505L-2

Overview

The CEL PS2505L-2 is a dual-channel transistor output optocoupler featuring high isolation voltage. It contains two independent NPN phototransistors driven by GaAs infrared LEDs. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward current rating of 80 mA. The device offers an insulation voltage of 5000 Vrms and operates within a temperature range of -55°C to +100°C. Power dissipation is rated at 120 mW.

Feature Summary

• Dual-channel configuration for simultaneous signal isolation
• High insulation voltage capability for safety-critical applications
• NPN phototransistor output structure

Applications

• AC input detection circuits
• Industrial control systems requiring galvanic isolation
• Power supply feedback loops

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm datasheet revisions match design requirements. Check for RoHS compliance variations across manufacturing lots. Validate package integrity upon receipt. Ensure storage conditions prevent moisture damage prior to soldering.

Selection Notes

Choose this component when dual-channel isolation is required in a compact form factor. Compare CTR specifications against load requirements. Verify thermal management capabilities for the intended operating environment. Consider pin compatibility with existing PCB layouts during integration planning.

Part Context

This part belongs to the NEPOC series from CEL, designed for general-purpose isolation tasks. It shares architectural similarities with single-channel variants like the PS2505L-1 but provides doubled channel density. The family targets cost-sensitive industrial and consumer electronics markets requiring reliable signal transfer across potential barriers.

Replacement Considerations

PS2505L-2-A is listed as a possible replacement. Verify pinout and electrical parameter equivalence before substitution.
