Overview
The SFH6345-X017T is a high-speed optocoupler featuring a GaAlAs infrared emitting diode and an integrated phototransistor detector. It provides 5300 Vrms isolation voltage with a data rate of 1 Mb/s. The device operates within a temperature range of -55°C to +100°C, supports a maximum forward current of 16 mA, and delivers a minimum current transfer ratio of 30%. Typical switching times are 300ns for both turn-on and turn-off.
Feature Summary
- High-speed signal transmission capability at 1 Mb/s
- Robust electrical isolation up to 5300 Vrms
- Wide operating temperature range suitable for industrial environments
Applications
- Industrial communication interfaces
- Isolated digital signal transmission
- Microprocessor system isolation
Procurement Notes
Verify the specific suffix X017T confirms the surface-mount SMD-8 package configuration. Confirm that the required current transfer ratio meets the 30% minimum specification for the target application circuit. Ensure compatibility with the 5300 Vrms isolation requirements of the design.
Selection Notes
Select this component when high-speed digital isolation is required in a compact surface-mount form factor. The 1 Mb/s data rate distinguishes it from standard logic output couplers. Consider the 8-SMD footprint constraints and the need for wide temperature stability in harsh operational conditions.
Part Context
This part belongs to the SFH6345 series of Vishay high-speed optocouplers. The series utilizes GaAlAs technology for efficient light emission. The X017T variant specifically denotes the tape-and-reel surface-mount packaging option, differing from through-hole DIP versions like the X016.
Replacement Considerations

FAQ
What is the typical switching time for the SFH6345-X017T?
The typical turn-on and turn-off times are both 300 nanoseconds.
Does the SFH6345-X017T include a base connection?
No, the SFH6345-X017T features a standard phototransistor output without a base terminal, unlike variants such as the 4N35-X017T.
