Overview
The FOD817C3SD is a surface-mount transistor output optocoupler from onsemi. It features a single channel with an NPN phototransistor output and SMD-4 package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, maximum collector current of 50 mA, and forward current of 50 mA. The device provides 5000 Vrms isolation voltage and operates within a temperature range of -55°C to +110°C. Typical rise and fall times are 4 µs and 3 µs respectively. Current transfer ratio ranges from 200% to 400%. Maximum power dissipation is 200 mW.
Feature Summary
- Provides galvanic isolation between input and output circuits using a phototransistor configuration.
- Designed for surface mount installation in compact electronic assemblies.
- Capable of handling high isolation voltages for safety-critical signal transmission.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic devices
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'SD' corresponds to the required tape and reel packaging format rather than tube packaging. Confirm that the manufacturer's RoHS compliance status aligns with project environmental requirements. Ensure the component's moisture sensitivity level is managed according to storage guidelines before soldering.
Selection Notes
Select this component when surface-mount technology is required for the FOD817 form factor. Consider the specific current transfer ratio range if precise gain is necessary for the application. Verify that the 70 V collector-emitter voltage rating meets the load requirements of the isolated circuit.
Part Context
This part belongs to the FOD817 series of phototransistor optocouplers manufactured by onsemi. It shares the standard pinout and functional characteristics of the legacy 817 family but utilizes a modern surface-mount package suitable for automated assembly processes.
Replacement Considerations
Compatible replacements include other surface-mount variants within the FOD817 series such as FOD817C3S or FOD817CS, provided the packaging type matches the design constraints.
