Overview
The PS2502L-2-E3-A is a dual-channel Darlington output optocoupler manufactured by CEL. It features an isolation voltage of 5000 Vrms and utilizes an 8-SMD package. The device provides high current transfer ratios, typically ranging from 200% to 600% at a forward current of 5 mA. It operates within a temperature range of -55°C to +100°C and includes UL recognition for safety compliance.
Feature Summary
- Dual-channel configuration with Darlington transistor outputs
- High isolation voltage rating of 5000 Vrms
- Wide operating temperature range suitable for industrial environments
- Surface-mount DIP-8 compatible packaging
Applications
- Industrial automation control systems
- Power supply feedback loops
- Solid-state relay driver circuits
- Microcontroller interface isolation
Procurement Notes
Verify the specific suffix E3-A against official datasheets to confirm lead-free status and pinout compatibility. Confirm availability as distribution status may vary. Ensure PCB footprint matches the 8-SMD specification before ordering.
Selection Notes
Select this component when dual-channel isolation is required in a compact surface-mount form factor. The Darlington output offers high gain, making it suitable for driving loads directly without additional amplification stages compared to standard transistor outputs.
Part Context
This part belongs to the PS2502L series of optocouplers from CEL. It shares architectural similarities with single-channel variants like the PS2501L but provides two independent channels in one package, enhancing board space efficiency for multi-signal isolation applications.
Replacement Considerations
Check for direct equivalents such as the PS2502L-1-E3-L-A or other Darlington optocouplers with matching 5000V isolation and 8-SMD packages. Verify pin-to-pin compatibility and current transfer ratio specifications before substitution.
