Overview
The PS2501L-1-F3-D-A is a single-channel transistor output optocoupler manufactured by CEL. It features a GaAs LED and an NPN silicon phototransistor for signal isolation. Key electrical parameters include a maximum collector-emitter voltage of 80V, a collector current of 50mA, and an isolation voltage of 5000Vrms. The device operates within a temperature range of -55°C to +100°C. Typical rise and fall times are 3µs and 5µs respectively. The unit is housed in a 4-SMD gull-wing package designed for surface mount applications.
Feature Summary
- Optical isolation between input and output circuits using a GaAs LED and NPN phototransistor
- High insulation voltage capability for safe signal transmission across potential differences
- Surface mount packaging design suitable for automated assembly processes
Applications
- Industrial control system signal isolation
- Power supply feedback loop monitoring
- Microcontroller interface protection
Procurement Notes
Verify the specific suffix D-A against official datasheets to confirm pinout and tape-and-reel specifications. Confirm RoHS compliance status through manufacturer documentation. Check availability as distribution channels may vary. Ensure the ordering part number matches the required package type and lead configuration before procurement.
Selection Notes
Select this component when high isolation voltage is required in a compact surface mount form factor. Consider the 50mA collector current limit for load driving capabilities. Evaluate the 5000Vrms isolation rating against system safety requirements. Compare switching speeds with other series options if faster response times are necessary for the application.
Part Context
This part belongs to the PS2501L series of photocouplers from CEL. The series includes variants with different packages and performance characteristics. The L designation typically indicates a lead bending or gull-wing style for surface mounting. This specific model integrates standard transistor output functionality within the broader family of optically coupled isolators.
Replacement Considerations
Cross-reference with PS2501L-1-F3-A for similar surface mount specifications. Verify compatibility with PS2501-1-W-A if DIP packaging is acceptable. Ensure replacement parts maintain equivalent isolation voltage and current transfer ratio requirements.
