Overview
The onsemi FOD817D300W is a single-channel, through-hole phototransistor output optocoupler in the FOD series. It features a 4-pin MDIP package with DC input capability. Key electrical parameters include a maximum forward voltage of 1.4V and a maximum input current of 50mA. The device offers an isolation voltage of 5000Vrms and operates within a temperature range of -55°C to 110°C. Typical rise and fall times are 18μs. Current transfer ratio specifications vary by source, with some documentation citing a minimum of 300% and others indicating a maximum of 6%. Certifications include C-UL, UL, and VDE.
Feature Summary
- Provides galvanic isolation between input and output circuits using a phototransistor configuration.
- Supports direct current input signals for logic interface applications.
- Complies with international safety standards including UL, VDE, and C-UL certifications.
Applications
- Signal isolation in industrial control systems
- Logic circuit interfacing
- Power supply feedback loops
Procurement Notes
Verify specific current transfer ratio requirements against official datasheets, as available sources cite varying minimum values such as 300%. Confirm package dimensions match the MDIP specification. Ensure compliance with required safety certifications like UL or VDE for the target application environment before finalizing procurement decisions.
Selection Notes
Select this component when high isolation voltage is required for single-channel DC signal transmission. Compare performance metrics against other FOD817 variants if different current transfer ratios or switching speeds are needed. Verify thermal management capabilities given the operating temperature range limits.
Part Context
This part belongs to the FOD817 family of optocouplers from onsemi. These devices are widely used for general-purpose isolation tasks. The 'D' suffix typically denotes specific current transfer ratio bins within the series. The '300W' suffix indicates the tape and reel packaging format.
Replacement Considerations
Direct substitutes may include other FOD817 variants with matching pinouts and isolation ratings. Verify compatibility regarding current transfer ratio ranges and package dimensions before substitution.
