Overview
The FOD817300W is a single-channel transistor output optocoupler from onsemi's FOD series, housed in a 4-pin MDIP package. It features an NPN phototransistor output with a maximum collector current of 50 mA and a collector-emitter voltage of 70 V. 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 18 μs. The minimum current transfer ratio is 50% at 5 mA input, with a maximum of 600%. It accepts DC input with a maximum forward current of 50 mA and a typical forward voltage of 1.4 V.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using a single phototransistor channel.
- Features fast switching performance with typical rise and fall times of 18 microseconds for signal transmission.
- Offers wide operating temperature range suitable for demanding industrial environments.
Applications
- Industrial process control systems requiring galvanic isolation
- Power supply feedback loops for circuit protection
- Signal interfacing between microcontrollers and high-voltage loads
Procurement Notes
Verify the specific suffix '300W' against official datasheets to confirm packaging configuration and compliance certifications. Ensure the procurement source is an authorized distributor to guarantee component authenticity and traceability. Check for RoHS compliance status if required by project specifications. Confirm lead times as availability may fluctuate based on manufacturing schedules.
Selection Notes
Select this component when high isolation voltage and moderate speed are required for single-channel applications. Compare current transfer ratio ranges against load requirements to ensure sufficient drive capability. Consider the through-hole MDIP package for PCB mounting constraints. Evaluate thermal management needs given the 110°C maximum junction temperature limit.
Part Context
This part belongs to the FOD817 family of general-purpose optocouplers. It shares functional similarities with other variants like FOD817C and FOD817B but differs in current transfer ratio specifications and packaging options. The FOD series is widely used in industrial and consumer electronics for signal isolation.
Replacement Considerations
FOD817C300W and FOD817B300 are potential substitutes within the same manufacturer's lineup. Verify pinout compatibility and electrical parameter margins before substitution. Other manufacturers offer equivalent DIP-4 optocouplers but require full specification cross-checking.
