Overview
The PS2581AL2-Q-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics Corporation. It features an NPN phototransistor output with a collector-emitter breakdown voltage of 80 V and a maximum DC forward current of 80 mA. The device provides high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +100°C. The typical current transfer ratio is 200% at 5 mA, with rise and fall times of 3 µs and 5 µs respectively. It is housed in a lead-free plastic DIP-4 package.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Wide operating temperature range suitable for demanding industrial environments
- Lead-free construction compliant with environmental directives
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal isolation in microprocessor interfaces
Procurement Notes
Verify the specific suffix Q-A against official Renesas documentation to confirm compliance requirements and marking details. Confirm component status as active or obsolete before procurement planning. Ensure the supplier provides valid traceability documents matching the manufacturer's part identification.
Selection Notes
Select this component when a single channel with 80V output voltage and 5000Vrms isolation is required. Consider the 200% CTR and 80mA input current limits for circuit design. Verify package compatibility with existing PCB layouts using the DIP-4 footprint specifications.
Part Context
This component belongs to the PS2581 series of transistor output optocouplers from Renesas Electronics. The series is designed for general-purpose isolation applications. The PS2581AL2 variant specifically offers higher current transfer ratio characteristics compared to standard versions, enhancing performance in low-input-current scenarios.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official Renesas documentation for qualified alternatives.
