Overview
The SFH615A-1X is a single-channel optocoupler manufactured by Isocom Components, featuring an infrared LED input and an NPN phototransistor output. It provides electrical isolation with a maximum forward voltage of 1.65V and supports a maximum input current of 60 mA. The device offers a typical rise time of 2 µs and a fall time of 11 µs. It ensures high reliability with an isolation voltage of 5300 Vrms and 7500 V peak. The component operates within a temperature range of -55°C to +100°C and is available in DIP-4 or SMD-4 packages.
Feature Summary
- Provides galvanic isolation between input and output circuits using infrared light transmission
- Features a standard NPN phototransistor output for reliable signal switching
- Complies with international safety standards including UL and VDE certifications
Applications
- Logic-to-logic isolation in noisy industrial environments
- Line receiver circuits for communication interfaces
- Programmable current level sensing applications
- Digital control systems for motors and servo machines
Procurement Notes
Verify the specific suffix designation (e.g., XG, X017T) to confirm the exact package type and current transfer ratio binning required for your design. Ensure that the selected variant matches the necessary insulation voltage and operating temperature range specifications. Cross-reference official datasheets to confirm compliance with RoHS directives and regional safety approvals before finalizing procurement orders.
Selection Notes
Select this component when a standard transistor output optocoupler is needed for general-purpose isolation. Consider the CTR range requirements; variants exist with different gain characteristics. Verify package compatibility with your PCB layout, choosing between through-hole DIP or surface-mount options based on assembly constraints and thermal management needs.
Part Context
This part belongs to the SFH615A series, which serves as a direct replacement for legacy Vishay components like the VO615A. Isocom manufactures these devices to meet industry-standard pinouts and electrical parameters, ensuring drop-in compatibility for existing designs while maintaining high reliability and performance consistency across production batches.
Replacement Considerations
The SFH615A-1X is functionally equivalent to the Vishay VO615A-1X series. When substituting, verify that the alternative part number maintains identical pin configurations and electrical ratings to ensure circuit continuity without redesign.
