Overview
The PS2805-1-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 plastic package. The device provides high isolation voltage of 2500 Vrms, ensuring reliable signal transmission between isolated circuits. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a forward current of 30 mA, and a typical forward voltage of 1.2 V. The package offers shielding against ambient light, making it suitable for high-density applications requiring robust electrical isolation.
Feature Summary
- Integrates GaAs LED and NPN phototransistor for efficient optical coupling
- Provides high insulation voltage capability for safe circuit isolation
- Features a shielded SSOP package to block ambient light interference
- Supports AC input response characteristics for versatile signal handling
Applications
- Programmable Logic Controllers (PLCs)
- Office Automation (OA) equipment
- Measurement instruments
- Mixed integrated circuits
Procurement Notes
Verify the specific suffix 'F3' corresponds to tape-and-reel packaging if automated assembly is required. Confirm RoHS compliance status through official datasheets as regulatory requirements may vary by region. Ensure the SSOP-4 footprint matches the target PCB design constraints. Check for any updated safety certifications such as UL or VDE approvals relevant to the end application's regulatory environment before finalizing procurement.
Selection Notes
Select this component when a single channel of high-isolation voltage is required in a minimal footprint. The NPN phototransistor output is suitable for digital switching applications. Consider the 80 V collector-emitter voltage rating for compatibility with downstream logic levels. The AC input response feature allows flexibility in driving circuit design compared to standard DC-only couplers. Evaluate thermal dissipation capabilities within the SSOP-4 package for continuous operation scenarios.
Part Context
This part belongs to the PS2805C series of high-isolation voltage photocouplers from Renesas. It shares architectural similarities with the PS2805C-1 but may differ in specific packaging or certification options. The series is designed for general-purpose industrial and commercial isolation tasks. It represents a legacy product line often maintained for existing designs requiring proven reliability and small form factors.
Replacement Considerations
Direct substitutes include the PS2805C-1-F3-A-M. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference with other single-channel SSOP-4 optocouplers if supply chain constraints exist.
