Overview
The PS2801-1-F3-Y-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward voltage of 1.1 V at a forward current of 5 mA. The device provides an isolation voltage of 2500 Vrms and has a power dissipation rating of 180 mW. It is housed in a compact SSOP-4 package.
Feature Summary
- Provides high insulation voltage for effective signal isolation between circuits.
- Utilizes a small and thin SSOP package design suitable for space-constrained applications.
- Features fast switching characteristics with defined rise and fall times.
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller input/output isolation
Procurement Notes
Verify the specific suffix 'Y-A' against official Renesas documentation to confirm pinout and packaging variations. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm availability status as distribution channels may list obsolete or limited stock items. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a single channel of isolation with NPN output is required. Consider the 80 V collector-emitter voltage limit for circuit design. Evaluate the 5 mA forward current requirement for drive circuitry. Compare performance metrics such as CTR and propagation delay against alternative optocouplers if higher speed or different output types are needed.
Part Context
This part belongs to the PS2801 series of transistor output optocouplers from Renesas Electronics. The series is characterized by high isolation voltage and compact SSOP packaging options. The PS2801-1 variant specifically denotes a single-channel configuration, distinguishing it from multi-channel versions like the PS2801-4.
Replacement Considerations
Publicly confirmed substitute part numbers for PS2801-1-F3-Y-A were not identified in the provided source material. Consult official Renesas documentation or authorized distributor databases for verified equivalents.
