Overview
The PS2521L-1-F3-A is a single-channel transistor output optocoupler manufactured by CEL. It features a surface-mount DIP-4 package and utilizes an NPN phototransistor output. Key electrical specifications include a maximum collector-emitter voltage of 80 V, a forward current rating of 150 mA, and a typical current transfer ratio of 80%. The device provides 5000 Vrms isolation voltage and operates within a temperature range of -55°C to +100°C.
Feature Summary
- High input drive capability with large forward current support
- Robust electrical isolation for signal integrity
- Surface-mount configuration for automated assembly
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the exact suffix against official datasheets to confirm pinout and packaging variations. Confirm RoHS compliance status as manufacturing processes evolve. Check for obsolete status or lifecycle changes before finalizing procurement plans. Ensure compatibility with existing board layouts and thermal management requirements.
Selection Notes
Select this component when high input current tolerance and moderate speed are required. Compare CTR ranges against specific circuit gain requirements. Verify that the surface-mount footprint matches the design constraints. Consider thermal dissipation limits in dense PCB layouts.
Part Context
This part belongs to the NEPOC series of high-isolation voltage photocouplers from CEL. The series includes both through-hole and surface-mount variants designed for reliable signal transmission across isolated boundaries. The PS2521L variant specifically addresses surface-mount assembly needs while maintaining high voltage withstand capabilities.
Replacement Considerations
Cross-reference with PS2521-1-A for through-hole equivalents. Verify functional compatibility with PS2521L-1-F3 regarding pinout and electrical characteristics before substitution.
