Overview
The PS2561A-1-V-L-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a plastic DIP package featuring lead bending for surface mount applications. The device provides high isolation voltage of 5000 Vrms, ensuring robust electrical separation between input and output circuits. Key electrical parameters include a collector-emitter breakdown voltage of 70 V minimum, a maximum forward current of 30 mA, and a power dissipation rating of 150 mW. The unit operates within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability of 5000 Vrms for enhanced safety and noise immunity
- Integrated GaAs LED and NPN silicon phototransistor for efficient optical coupling
- Lead-bending gull-wing configuration designed for surface mount technology
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Communication interface circuits
Procurement Notes
Verify the specific suffix 'V-L-A' against official datasheets to confirm lead form and compliance status. Confirm availability as distribution channels may list obsolete or limited stock variants. Ensure the supplier provides valid traceability documentation matching the manufacturer's specifications before finalizing orders.
Selection Notes
Select this component when surface mount assembly is required alongside high-voltage isolation needs. Compare the 70 V collector-emitter breakdown voltage against circuit requirements. Consider the 5000 Vrms insulation rating for safety-critical designs. Verify thermal management capabilities within the specified operating temperature range.
Part Context
This part belongs to the NEPOC series of photocouplers from CEL. It shares architectural similarities with other PS2561 family members but differs in packaging and lead configuration. The series emphasizes cost-performance balance while maintaining strict safety certifications including UL, CSA, and BSI approvals for global deployment.
Replacement Considerations
Cross-reference with PS2561AL-1-E3 or PS2561AL1-1 variants for equivalent performance. Verify pinout compatibility and isolation voltage ratings before substitution. Consult official replacement lists for discontinued components.
