Overview
The SFH618A-4X001 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a maximum collector-emitter voltage of 55 V and a maximum collector current of 100 mA. The device provides high isolation capability with an insulation voltage of 5300 Vrms. Key electrical parameters include a forward current of 60 mA, a forward voltage of 1.5 V, and a collector-emitter saturation voltage of 400 mV maximum. The component operates within a temperature range of -55°C to +100°C and is housed in a PDIP-4 through-hole package.
Feature Summary
- High isolation voltage rating for safe signal transmission across potential barriers
- High current transfer ratio ensuring efficient signal coupling between input and output circuits
- Low coupling capacitance designed to minimize noise interference in high-speed applications
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops for voltage regulation
- Signal transmission in noisy electromagnetic environments
Procurement Notes
Verify the specific CTR binning code suffix (e.g., 4X001) against the manufacturer's datasheet to ensure compliance with required current transfer ratio tolerances. Confirm that the PDIP-4 through-hole package aligns with the target PCB footprint and assembly process specifications before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and robust current handling are required in a standard DIP package. Compare the 55 V collector-emitter voltage limit against circuit requirements. Ensure the 100 mA maximum collector current exceeds the load demands. Verify thermal management capabilities within the specified operating temperature range for the intended application environment.
Part Context
This part belongs to the SFH618 family of optocouplers from Vishay, which are characterized by high current transfer ratios and low coupling capacitance. The SFH618A series specifically utilizes a DIP package configuration, distinguishing it from surface-mount variants like the SFH6186. These components are engineered for reliable performance in industrial and commercial isolation applications.
Replacement Considerations
Cross-reference with SFH617A-4X001 for similar DIP packaging but verify differences in collector-emitter voltage ratings and current transfer ratio ranges. Check VO618A-4X016 for alternative sourcing while noting potential variations in power dissipation and voltage specifications.
