Overview
The SFH618A-3XG is a single-channel optocoupler featuring an infrared LED and NPN silicon phototransistor. It utilizes a 4-pin DIP package for through-hole mounting. Key electrical parameters include a maximum forward voltage of 1.5V, a typical rise time of 3.5µs, and a typical fall time of 5µs. The device offers high isolation with 5300Vrms and 7500V peak ratings. Current transfer ratios range from 63% to 320% at 1mA input, with a minimum of 32% at 0.5mA. It supports a collector-emitter breakdown voltage of 55V minimum.
Feature Summary
- High current transfer ratio capability for efficient signal transmission
- Low input current requirement reducing power consumption
- High isolation voltage ensuring robust circuit protection
- Space-efficient dual in-line plastic packaging
Applications
- General purpose digital signal isolation
- Microcontroller interface circuits
- Industrial control systems requiring galvanic isolation
Procurement Notes
Verify the specific suffix (e.g., -G, -SM) against the required lead spread or surface mount configuration. Confirm RoHS compliance status as indicated in official documentation. Ensure the manufacturer designation matches Isocom Components specifications for the SFH618A series before procurement.
Selection Notes
Select this component when low input current operation is critical. The high CTR range suits applications needing reliable switching with minimal drive current. Verify that the 55V collector-emitter voltage meets the load requirements. Consider the DIP-4 package constraints for PCB layout.
Part Context
This part belongs to the SFH618A series of low input current phototransistor optocouplers. It is manufactured by Isocom Components and is designed for space-efficient applications. The series includes variants with different lead spreads and mounting options.
Replacement Considerations
Direct substitutes may include other SFH618A variants with compatible pinouts. Verify electrical parameters such as CTR and isolation voltage match the original design requirements before substitution.
