Overview
The SFH6286-4X001T is a surface-mount optoisolator featuring one channel with a phototransistor output. It provides an isolation voltage of 5300Vrms and supports AC or DC input. The device operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum forward current of 50mA, a typical forward voltage of 1.1V, and a collector-emitter saturation voltage of 400mV. The current transfer ratio ranges from 160% to 500% at 1mA. Typical switching times are 3.5µs rise and 5µs fall.
Feature Summary
- High isolation voltage capability for robust circuit separation
- Integrated gallium arsenide infrared-emitting diode coupled to a phototransistor
- Supports both AC and DC input signal types
- Designed for surface mount applications in compact form factors
Applications
- Industrial control systems requiring high-voltage isolation
- Power supply feedback loops
- Signal isolation in communication interfaces
- Microcontroller input interfacing with high-voltage domains
Procurement Notes
Verify the specific suffix 'X001' against official Vishay documentation to confirm exact packaging and tape specifications. Ensure compatibility with reflow soldering profiles defined in the datasheet. Confirm RoHS compliance status for your region's regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and AC/DC input flexibility are required. Consider the 160-500% current transfer ratio for logic level interfacing. Evaluate thermal management needs given the 100°C maximum operating temperature. Verify that the 4-SMD package fits the available PCB footprint constraints.
Part Context
This part belongs to the SFH series of optocouplers from Vishay Semiconductor Opto Division. It is designed for general-purpose isolation tasks where space-saving surface mount technology is preferred over through-hole alternatives. The series offers various isolation voltages and output configurations to suit different application demands.
Replacement Considerations
Check for direct substitutes within the SFH6286 family or other Vishay SMD optocouplers with matching 5300Vrms isolation and transistor output. Verify pinout compatibility and current transfer ratio ranges before substitution.
