Overview
The PS2802-1-F3-L-A is a single-channel NPN Photodarlington transistor output optocoupler manufactured by Renesas Electronics. It features an SSOP-4 surface-mount package with 2500 Vrms insulation voltage. The device supports a maximum collector current of 90 mA and a collector-emitter voltage of 40 V. It offers a high current transfer ratio of 2000% with a forward current of 5 mA. Operating temperatures range from -55°C to +100°C, with power dissipation rated at 180 mW.
Feature Summary
- High gain NPN photodarlington output for sensitive signal detection
- Robust 2500 Vrms basic isolation barrier between input and output
- Compact SSOP-4 surface mount footprint for space-constrained designs
Applications
- Industrial control system signal isolation
- Power supply feedback loop circuits
- Microcontroller interface isolation
Procurement Notes
Verify component authenticity through authorized channels due to limited availability status in some regions. Confirm RoHS compliance details via official datasheets before integration. Ensure storage conditions maintain moisture sensitivity levels according to manufacturer guidelines for SMD packages.
Selection Notes
Select this model when high current transfer ratio is required for low input drive currents. The photodarlington architecture provides superior sensitivity compared to standard phototransistors. Verify that the 40V collector-emitter voltage rating meets the specific circuit load requirements.
Part Context
This component belongs to the PS2802 series of transistor output optocouplers. It shares the same core photodetector technology as other variants but differs in packaging and specific electrical tolerances. The series is designed for general-purpose digital isolation applications requiring reliable performance across wide temperature ranges.
Replacement Considerations
Cross-reference with PS2802-1-V-F3-A for similar electrical characteristics. Verify pinout compatibility and thermal dissipation requirements when substituting components in existing PCB layouts.
