Overview
The SFH6286-3T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an aluminum gallium arsenide infrared emitting diode optically coupled to a silicon planar phototransistor, housed in a compact 4-SMD (gull-wing) package. The device provides high isolation voltage of 5300 Vrms and supports both AC and DC input signals. Key electrical parameters include a collector-emitter saturation voltage of 400 mV maximum, a forward current of 50 mA maximum, and a CTR range of 100% to 320%. Operating temperatures span from -55°C to +100°C.
Feature Summary
- High current transfer ratio for efficient signal transmission
- AC input capability with integrated rectifier configuration
- Low coupling capacitance for improved noise immunity
- RoHS compliant surface mount construction
Applications
- Signal isolation between microcontrollers and power circuits
- Solid-state relay driver interfaces
- Industrial control system isolation barriers
- Power supply feedback loop isolation
Procurement Notes
Verify the specific suffix '3T' corresponds to the required CTR binning and packaging format. Confirm RoHS compliance status through official manufacturer documentation. Ensure the 4-SMD gull-wing footprint matches PCB design requirements. Check for any recent PCN updates regarding assembly or material changes.
Selection Notes
Select this component when AC input compatibility is required alongside high CTR performance. Compare against SFH6286-4T if higher CTR margins are needed. Verify thermal dissipation capabilities within the 150 mW power rating. Ensure isolation voltage requirements do not exceed 5300 Vrms limits.
Part Context
This part belongs to the SFH628 series, which includes DIP and SMD variants. The SFH6286 specifically denotes the SMD version with AC input capability. It shares architectural similarities with SFH6186 but offers enhanced CTR specifications. The family is designed for general-purpose isolation applications requiring reliable signal transfer across electrical boundaries.
Replacement Considerations
SFH6286-4T offers higher CTR range (160%-500%) with identical pinout and package. SFH6286-3 is the DIP-4 equivalent version. Cross-reference datasheets for exact parameter matching before substitution.
