Overview
The CEL PS2806-1-F3 is a single-channel optoisolator featuring a Darlington transistor output. It supports both AC and DC input signals, making it versatile for various isolation applications. The device offers a maximum output voltage of 40V and can handle an output current of 90mA per channel. Typical forward voltage is 1.1V. It provides high isolation voltage capability of 2500Vrms.
Feature Summary
- High isolation voltage rating of 2500Vrms for robust signal separation
- Supports AC and DC input signal types for flexible integration
- Darlington transistor output configuration for high gain
- Compact 4-SOP package design
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
- Motor drive control isolation
Procurement Notes
Verify the specific suffix F3 indicates the tape and reel packaging format when ordering. Confirm the manufacturer is CEL and not NEC/Renesas, as part numbers may overlap across brands. Ensure the 4-SOP package footprint matches your PCB design requirements before finalizing procurement.
Selection Notes
Select this component when AC input response is required alongside Darlington output characteristics. The 90mA output current capacity suits moderate load driving needs. Verify that the 40V maximum output voltage meets your circuit's voltage constraints. Consider the 2500Vrms isolation rating for safety compliance in mains-connected applications.
Part Context
This part belongs to the PS2806 series of optocouplers from CEL. It is functionally similar to other devices in the family but distinguished by its specific output type and packaging. The series is designed for general-purpose isolation tasks where high input-output voltage separation is critical.
Replacement Considerations
Check datasheets for direct pin-compatible substitutes from other manufacturers. Verify that any replacement maintains the same Darlington output configuration and 2500Vrms isolation rating. Ensure the replacement part supports AC input operation if that feature is essential to your design.
