Overview
The SFH6186-4X001T is a single-channel transistor output optocoupler from Vishay, designed for high-voltage isolation. It features an NPN phototransistor output with a current transfer ratio ranging from 160% to 320% at 1mA input. The device supports a maximum collector-emitter voltage of 55V and a continuous collector current of 50mA. Electrical characteristics include a forward voltage of 1.1V typical, with a maximum DC forward current of 60mA. Isolation capability is rated at 5300Vrms. Switching times are specified as 3.5µs rise time and 5µs fall time. The component operates within a temperature range of -55°C to +100°C and is housed in a compact 4-SMD surface-mount package.
Feature Summary
- Provides galvanic isolation between input and output circuits using infrared LED and phototransistor technology.
- Features a high current transfer ratio suitable for efficient signal transmission at low input currents.
- Offers robust insulation voltage rating for safe operation in high-potential environments.
- Designed for surface-mount assembly to facilitate automated PCB manufacturing processes.
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical isolation between different system grounds
Procurement Notes
Verify the specific suffix X001T against the official Vishay datasheet to confirm the exact CTR binning and packaging configuration. Ensure that the 4-SMD footprint matches the target PCB design guidelines. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and moderate speed are required for single-channel applications. Consider the 160-320% CTR range for circuit biasing calculations. Evaluate the 4-SMD package size constraints against available board space. Compare switching times against system timing requirements to ensure adequate performance margins.
Part Context
This part belongs to the SFH6186 series of transistor output optocouplers manufactured by Vishay Semiconductor Opto Division. The series offers various CTR bins and packaging options to suit different application needs. The SFH6186-4X001T specifically denotes the SMD variant with defined electrical parameters for industrial and consumer electronics.
Replacement Considerations
Compatible substitutes within the same family include SFH6186-3T and SFH6186-5T, which offer different current transfer ratio ranges. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with SFH618A series parts if through-hole packaging is acceptable for the application.
