Overview
The PS2806-1-F3-A is a single-channel optoisolator manufactured by Renesas Electronics. It features a Darlington phototransistor output and provides an isolation voltage of 2500 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a forward current of 50 mA, and a forward voltage of 1.4 V. The device operates within a temperature range of -55°C to +100°C and has a power dissipation of 120 mW. It is housed in a compact 4-pin SSOP package with a 1.27 mm pin pitch.
Feature Summary
- High isolation voltage capability for safe signal transmission
- Compact and thin small-outline package design
- AC input response functionality
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for obsolescence notices as this part may be subject to limited availability or replacement recommendations. Ensure packaging specifications match production requirements.
Selection Notes
Select this component when high isolation voltage and AC input response are required in a compact form factor. Consider the Darlington output configuration for higher current transfer ratios compared to standard phototransistors. Verify thermal management needs given the 120 mW power dissipation rating in the SSOP-4 package.
Part Context
This component belongs to the PS2806 series of optocouplers from Renesas. The series includes variants with different channel counts and output types. The PS2806-1-F3-A specifically denotes the single-channel version with Darlington output and specific tape-and-reel packaging suffixes.
Replacement Considerations
Official documentation indicates that newer designs should consider alternative components. Verify cross-reference compatibility carefully, ensuring isolation voltage and pinout configurations match exactly before substitution.
