Overview
The PS2801C-1Y-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a compact SSOP-4 surface-mount package. The device provides high isolation voltage of 2500 Vrms and supports a maximum collector-emitter voltage of 80 V. Key electrical characteristics include a typical rise time of 3 µs and fall time of 5 µs, with a forward current rating of 50 mA. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- Integrates GaAs LED and NPN phototransistor for signal isolation
- Provides high insulation voltage capability for safety compliance
- Features fast switching speed suitable for digital signal transmission
- Utilizes shielded SSOP package to block ambient light interference
Applications
- Programmable Logic Controllers (PLCs)
- Measurement instruments
- Power supply circuits
- Mixed-signal integrated circuits
Procurement Notes
Verify the specific suffix 'Y' against official Renesas documentation to confirm tape-and-reel packaging specifications and pin configuration compatibility. Ensure the component status is reviewed as some variants in this series may carry Not Recommended for New Designations. Confirm RoHS compliance and safety certifications such as UL or CSA are required for the target application before procurement.
Selection Notes
Select this component when single-channel isolation with high-speed switching is required in space-constrained designs. The SSOP-4 package offers a small footprint suitable for dense PCB layouts. Consider the 80 V collector-emitter voltage limit and 50 mA forward current requirements to ensure proper circuit biasing. Verify that the 2500 Vrms isolation rating meets the safety standards of the end equipment.
Part Context
This part belongs to the PS2801 family of high-isolation voltage photocouplers from Renesas. The family includes single-channel (PS2801-1/PS2801C-1) and four-channel (PS2801-4) variants. These devices are designed for applications requiring reliable galvanic isolation between control circuits and high-voltage loads, utilizing standard plastic SSOP packages for surface mounting.
Replacement Considerations
Publicly confirmed substitute part numbers for PS2801C-1Y-F3-A were not identified in the provided source material. Cross-reference with other single-channel transistor output optocouplers in the same package only if official substitution data is available.
