Overview
The SFH618A-3X001 is a single-channel transistor output optocoupler from Vishay, featuring an infrared LED and NPN phototransistor in a DIP-4 package. It provides electrical isolation with a rated voltage of 5300Vrms. The device supports a maximum DC forward current of 60 mA and a collector current of 50 mA, with a typical forward voltage of 1.1 V. Key timing parameters include a turn-on time of 6 μs and a turn-off time of 5.5 μs. The current transfer ratio ranges from 100% to 200% at 1 mA input. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using infrared light transmission.
- Integrates an infrared LED emitter with an NPN phototransistor for efficient signal coupling.
- Designed for digital logic transmission and impedance transformation applications.
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical insulation isolation between circuits and systems
Procurement Notes
Verify the specific suffix 3X001 to ensure correct packaging and binning specifications. Confirm that the DIP-4 through-hole package matches the target PCB footprint. Check RoHS compliance status if required by project standards. Ensure the 5300Vrms isolation rating meets safety requirements for the intended application environment.
Selection Notes
Select this component when a single-channel isolation solution with moderate speed is required. The 50 mA collector current capability suits general-purpose switching tasks. Consider the 100-200% CTR range for reliable triggering at low input currents. Compare against SFH618A variants if different packaging or CTR bins are needed.
Part Context
This part belongs to the SFH618A series of Vishay's transistor output optocouplers. It shares the same core semiconductor structure as other members but differs in packaging and performance binning. The series is widely used in industrial and consumer electronics for galvanic isolation.
Replacement Considerations
SFH618A-2 offers a lower CTR range (63-125%). SFH618A-5 provides a higher CTR range (250-500%). SFH618A-4X016 features a CTR of 160-320%. Verify pinout compatibility before substitution.
