Overview
The PS2861B-1Y-L-A is a single-channel transistor output photocoupler manufactured by CEL. It features an isolation voltage of 3750Vrms and a creepage distance of 5mm. The device provides a minimum current transfer ratio of 100% at 5mA input, with a maximum CTR of 300%. It is housed in a compact 4-pin SSOP package.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes a transistor output configuration for digital signal transmission
- Designed for compact integration within space-constrained electronic assemblies
Applications
- Industrial control systems requiring basic signal isolation
- Power supply feedback loops for circuit protection
- Communication interface isolation for data integrity
Procurement Notes
Verify the specific suffix 'L-A' against official manufacturer documentation to confirm pinout and packaging compatibility. Confirm availability status as this variant may be discontinued or superseded by newer revisions. Ensure compliance with relevant safety standards required for your specific application environment before procurement.
Selection Notes
Select this component when a low-cost, single-channel isolation solution is sufficient for applications not requiring high-speed switching. Evaluate the 3750Vrms isolation rating against system transient voltage requirements. Consider the SSOP package dimensions for PCB layout constraints and thermal management needs during design integration.
Part Context
This part belongs to the PS2861 series of optocouplers from CEL. These devices are designed for general-purpose isolation tasks. The series typically includes variants with different output types and packaging options to suit various industrial and consumer electronics applications requiring galvanic separation.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific CEL model were not identified in available documentation. Verify functional equivalence with other 3750Vrms transistor output optocouplers if direct replacement is necessary.
