PS2815-4-A

Overview

The PS2815-4-A is a four-channel transistor output optocoupler manufactured by CEL (Renesas). It features an AC input response and high current transfer ratio, typically 200% at ±1 mA. The device provides 2500 Vrms isolation voltage between input and output channels. It is housed in a 16-pin SSOP package with a surface mount configuration. The component supports a collector-emitter voltage of 40V and is designed for applications requiring multiple isolated signal paths.

Feature Summary

• Four independent channels for multi-signal isolation
• AC input response capability
• High current transfer ratio performance
• 2500 Vrms insulation voltage

Applications

• Industrial control systems
• Power supply feedback loops
• Communication interface isolation

Procurement Notes

Verify the manufacturer designation as CEL or Renesas on the datasheet, as both entities are associated with this part number. Confirm the package type is 16-SOIC or SSOP matching the specific suffix. Check the lifecycle status, as listings indicate obsolete or limited availability. Ensure the AC input feature requirement aligns with the circuit design before procurement.

Selection Notes

Select this component when multiple isolated channels are required within a single package footprint. The AC input response makes it suitable for circuits where the input signal polarity may vary. Verify that the 40V collector-emitter voltage rating meets the load requirements. Consider the thermal dissipation capabilities if operating near maximum ratings.

Part Context

This part belongs to the PS2815 series of photocouplers. It shares functional similarities with the PS2815-1 but offers four channels instead of one. The series is known for high CTR and AC input compatibility. It is distinct from the PS2801 series which typically has different channel counts and pinouts.

Replacement Considerations

Direct substitutes include the PS2815-1 for single-channel needs, though pinout differs. Other quad-channel optocouplers from different manufacturers may require schematic redesign. Verify pin compatibility and electrical parameters before substitution.
