Overview
The PS2561L2-1-V-L-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN phototransistor output and operates with a maximum collector-emitter voltage of 80 V and a collector current of 50 mA. The device provides high isolation voltage of 5000 Vrms and supports a forward current of up to 30 mA. Typical current transfer ratio is 200%, with rise and fall times of 3 μs and 5 μs respectively. It utilizes a surface-mount 4-SMD gull-wing package and functions within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability of 5000 Vrms for safe signal transmission across potential differences.
- Surface-mount gull-wing lead configuration designed for long creepage distance requirements.
- Fast switching performance with typical rise time of 3 μs and fall time of 5 μs.
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback circuits
- Signal isolation in microprocessor interfaces
Procurement Notes
Verify the specific suffix 'V-L-A' against official CEL documentation to confirm lead bending type and packaging specifications. Ensure compatibility with surface mount assembly processes. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before integration into production lines.
Selection Notes
Select this component when high isolation voltage and long creepage distance are critical design requirements. The gull-wing package facilitates automated surface mounting while maintaining safety standards. Consider the 50 mA output current capacity and 80 V breakdown voltage for circuit load matching. Verify thermal management needs within the specified operating temperature range.
Part Context
This part belongs to the PS2561 series of high isolation voltage single transistor type photocouplers. The series includes various package options such as DIP and SMD types. The PS2561L2 variant specifically addresses applications needing extended creepage distances via its specialized lead form, distinguishing it from standard surface mount counterparts.
Replacement Considerations
Public confirmed substitute part numbers: PS2561L2-1-V-A (CEL), PS2561L2-1-H-A (CEL). Verify pinout and electrical parameters match before substitution.
