Overview
The FOD817D300 is a single-channel transistor output optocoupler from the FOD series, manufactured by Fairchild Semiconductor. It features a gallium arsenide infrared emitting diode coupled to a silicon phototransistor in a 4-pin MDIP package. Key electrical parameters include a maximum forward voltage of 1.4V, a minimum current transfer ratio of 300%, and an isolation voltage of 5000Vrms. The device supports a maximum input current of 50mA, with typical rise and fall times of 18μs. It operates within a temperature range of -55°C to 110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using infrared LED and phototransistor technology.
- Features a compact 4-pin dual in-line package suitable for through-hole mounting.
- Offers high operating temperature capability compared to standard counterparts.
- Complies with lead-free IR reflow soldering standards.
Applications
- Power supply regulators
- Digital logic inputs
- Microprocessor inputs
Procurement Notes
Verify that the specific suffix '300' corresponds to the required Current Transfer Ratio (CTR) bin of 300-600%. Confirm package type compatibility, as 'D300W' variants may exist. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Cross-reference datasheet revision dates to confirm parameter consistency.
Selection Notes
Select this component when a high CTR bin is required for signal integrity in digital interfaces. The 5000Vrms isolation rating suits applications demanding robust galvanic separation. Consider the 18μs switching speed for moderate frequency applications. Verify thermal management needs given the 110°C maximum junction temperature limit.
Part Context
This part belongs to the FOD817 series of phototransistor optocouplers. The 'D' designation indicates a specific CTR group (300-600%), while '300' often denotes tape-and-reel packaging. The series is known for high isolation voltage and reliability in industrial control environments.
Replacement Considerations
Equivalent parts include FOD817D and FOD817DSD. Verify pinout compatibility and CTR specifications before substitution. Note that Fairchild Semiconductor is now part of onsemi; check for updated ordering suffixes.
