Overview
The PS2811-1-F3 is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output with a collector-emitter voltage rating of 40V and a maximum collector current of 40mA. The device offers a high Current Transfer Ratio (CTR) ranging from 100% to 400% at a forward current of 1mA. It provides an isolation voltage of 2500Vrms and operates within a temperature range of -55°C to 100°C. The component is housed in a thin SSOP-4 package.
Feature Summary
- High Current Transfer Ratio for low input current applications
- Wide operating temperature range suitable for industrial environments
- Thin SSOP-4 package design for space-constrained PCB layouts
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix 'F3' against the manufacturer's latest datasheet to confirm pinout compatibility and packaging specifications. Ensure that the CTR binning requirements match your circuit design needs, as variations may exist between production lots. Confirm RoHS compliance status if required by your assembly standards.
Selection Notes
Select this component when high CTR is necessary to drive loads with minimal LED current. The 40V output voltage rating suits low-voltage logic interfaces. Consider the thermal characteristics and package size relative to available board space. Compare performance metrics against alternative optocouplers if higher isolation voltages or different output types are required.
Part Context
This part belongs to the PS2811 series of high-CTR optocouplers. It is functionally similar to parts from other manufacturers like Renesas, which also produce variants under the same base model number. The series is designed for general-purpose isolation where efficiency and speed are prioritized over extreme voltage ratings.
Replacement Considerations
Direct substitutes include PS2811-1-A and PS2811-1-V-F3-A. Verify pinout and electrical parameters before substitution. Cross-reference with Renesas PS2811-1-F3-M-A for equivalent specifications.
