Overview
The SFH6345-X009 is a high-speed optocoupler featuring a single channel with a phototransistor output. It utilizes a GaAlAs infrared emitting diode optically coupled to an integrated photo detector, housed in an 8-SMD surface-mount package. The device supports data rates up to 1 Mb/s and provides an isolation voltage of 5300 Vrms. Key electrical parameters include a minimum current transfer ratio of 19% at 16 mA input, a maximum forward current of 25 mA, and a typical propagation delay of 300 ns for both turn-on and turn-off times. Operating temperature ranges from -55°C to +100°C.
Feature Summary
- High-speed operation supporting data rates up to 1 Mb/s
- Integrated phototransistor output for efficient signal transmission
- Robust insulation capability with 5300 Vrms isolation voltage
- Wide operating temperature range suitable for demanding environments
Applications
- Industrial communication systems requiring galvanic isolation
- Data acquisition circuits with high noise immunity needs
- Power supply feedback loops in switching regulators
- Signal isolation in microcontroller interface circuits
Procurement Notes
Verify the specific suffix designation against official Vishay documentation to confirm package type and performance characteristics. Ensure compliance with RoHS3 standards and check moisture sensitivity level requirements during storage and handling. Confirm lead times and availability through authorized distributors as manufacturing schedules may vary.
Selection Notes
Select this component when high-speed digital isolation is required in a compact surface-mount form factor. Consider the 1 Mb/s data rate capability and low propagation delay for timing-sensitive applications. Evaluate the 5300 Vrms isolation rating against system safety requirements and ensure the operating temperature range aligns with environmental conditions.
Part Context
The SFH6345 series represents Vishay's high-performance optocoupler lineup designed for modern electronic systems. This specific model variant integrates advanced semiconductor technology to deliver reliable signal transmission across isolation barriers. The series is recognized for its consistency in electrical parameters and adherence to international safety standards.
Replacement Considerations
Direct substitutes within the same family include SFH6345-X016 (PDIP) and SFH6345-X019T (SMD). Verify pin compatibility and thermal characteristics before substitution. Cross-model generic features should not be assumed; consult datasheets for precise parameter matching.
