Overview
The FOD070L is a single-channel optocoupler from onsemi's FOD series, housed in an 8-pin SOIC package. It features a DC input and utilizes a split Darlington transistor output configuration with a base terminal for enhanced performance. The device provides electrical isolation rated at 2500 Vrms. Key electrical parameters include a maximum forward voltage of 1.8V and a typical current transfer ratio of 6000% at a forward current of 10mA. It operates within a temperature range of -40°C to 100°C.
Feature Summary
- Split Darlington output architecture enables high current gain and low input current requirements
- Integrated base terminal allows for adjustable speed and sensitivity control
- Provides robust galvanic isolation between input and output circuits
Applications
- Industrial automation control systems
- Solid-state relay driver circuits
- Microcontroller interface isolation
Procurement Notes
Verify the specific ordering suffix against the official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets all required regulatory standards for your target market. Check for any recent lifecycle status updates or obsolescence notices directly from onsemi before finalizing procurement plans.
Selection Notes
Select this component when high current transfer ratio is critical for driving loads with minimal input power. The split Darlington design offers superior linearity compared to standard phototransistor outputs. Ensure the application voltage does not exceed the collector-emitter breakdown limits specified in the electrical characteristics table.
Part Context
This part belongs to the FOD series of optocouplers, which are designed for general-purpose isolation applications. The FOD070L specifically targets scenarios requiring high gain and fast switching speeds. It complements other devices in the family by offering a balance of performance and cost-effectiveness for industrial and commercial electronics.
Replacement Considerations
The FOD070L is listed as obsolete. Verify compatible replacement part numbers from onsemi or equivalent manufacturers that match the 8-SOIC package and split Darlington output configuration.
