Overview
The PS2801C-1-V-F3-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 30 mA, and a power dissipation of 180 mW. The device provides an isolation voltage of 2500 Vrms with a typical current transfer ratio of 400%. Switching characteristics specify a rise time of 5 µs and a fall time of 7 µs. It is housed in an SSOP-4 surface-mount package.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes a shielded SSOP package to block ambient light interference
- Integrates a GaAs LED with an NPN silicon phototransistor for signal transmission
Applications
- Industrial control systems requiring signal isolation
- Measurement instruments needing circuit separation
- Power supply feedback loops for safety compliance
Procurement Notes
Verify the specific suffix 'V' against official Renesas documentation to confirm lead-free status and RoHS compliance details. Confirm availability as distribution channels may list this component as obsolete or end-of-life. Ensure the SSOP-4 footprint matches the target PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when a single channel of isolation is required with moderate speed switching capabilities. The 80 V collector-emitter voltage rating suits low-voltage logic interfacing. Verify that the 5 mA forward current requirement aligns with the driving circuit's output capability. Consider the thermal limits of the SSOP-4 package for high-density board layouts.
Part Context
This part belongs to the PS2801C series of high-isolation voltage photocouplers. The series is designed for applications demanding compact size and reliable signal transmission across isolated boundaries. The PS2801C variant specifically denotes the single-channel configuration within the broader family of available channel counts.
Replacement Considerations
Consult official cross-reference lists for direct replacements. Verify pinout compatibility and electrical parameter equivalence for any substitute components.
