PS2801-4-F4-A

Overview

The PS2801-4-F4-A is a four-channel transistor output optocoupler manufactured by CEL. It features an infrared emitting diode optically coupled to NPN phototransistors in a 16-pin SSOP package with a 1.27 mm pin pitch. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a forward current of 50 mA, and an isolation voltage of 2500 Vrms. The device operates within a temperature range of -55°C to +100°C, with a typical rise time of 3 µs and fall time of 5 µs.

Feature Summary

• Four independent channels for multi-signal isolation
• High insulation voltage capability
• Compact surface-mount packaging

Applications

• Industrial system controllers
• Measurement instruments
• Mixed substrate high-density installation

Procurement Notes

Verify the specific suffix F4-A against official datasheets to confirm pinout and packaging variations. Confirm RoHS compliance status as required by project specifications. Check manufacturer lifecycle status for long-term availability assurance before finalizing design-in decisions.

Selection Notes

Select this component when multiple isolated signal paths are required in a compact form factor. Ensure the 80 V collector-emitter voltage rating exceeds the load requirements. Verify that the 2500 Vrms isolation rating meets safety standards for the target application environment.

Part Context

This part belongs to the PS2801 series of transistor output optocouplers. It shares architectural similarities with single-channel variants like the PS2801-1 but provides quad-channel integration. The series is designed for general-purpose isolation in space-constrained electronic designs.

Replacement Considerations

Direct substitutes may include other quad-channel optocouplers with compatible pinouts and electrical ratings. Verify compatibility with existing PCB footprints and thermal management requirements when considering alternative manufacturers.
