PS2815-4-F3-L-A

Overview

The PS2815-4-F3-L-A is a four-channel transistor output optocoupler manufactured by CEL. It features an AC/DC input configuration with NPN phototransistor outputs. The device provides 2500 Vrms isolation voltage and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum forward current of 50 mA, a collector-emitter saturation voltage of 300 mV, and a power dissipation of 120 mW. It is housed in a surface-mount 16-SOIC package.

Feature Summary

• Four independent channels for multi-circuit isolation
• Compatible with both AC and DC input signals
• High current transfer ratio performance
• Wide operating temperature range

Applications

• Industrial control systems
• AC load switching circuits
• Multi-channel signal isolation interfaces

Procurement Notes

Verify the specific suffix L-A against official datasheets to confirm the 16-SOIC surface mount package and lead-free status. Confirm availability as distribution status may vary. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when four isolated channels are required for AC or DC input applications. The high CTR and low saturation voltage support efficient switching. Verify that the 2500 Vrms isolation rating meets system safety standards. Ensure the 16-SOIC package fits the design constraints.

Part Context

This part belongs to the PS2815 series of high CTR optocouplers designed for robust isolation. The four-channel configuration allows compact design in multi-line communication or control systems. It serves as a replacement for legacy discrete isolation solutions in industrial environments requiring reliable signal transmission across potential differences.

Replacement Considerations

PS2815-4-F3-A is a confirmed substitute part number within the same family.
