Overview
The SFH628A-3X016 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a current transfer ratio ranging from 100% to 320%. The device provides high isolation voltage of 5300 Vrms and supports through-hole installation in a DIP-4 package. Key electrical parameters include a maximum collector-emitter voltage of 55 V, a maximum collector current of 100 mA, and a forward voltage of 1.5 V at a forward current of 50 mA. Dynamic characteristics specify a rise time of 3.5 µs and a fall time of 5 µs. Power dissipation is rated at 150 mW, with an operating temperature range from -55°C to +100°C.
Feature Summary
- High current transfer ratio for efficient signal transmission
- High isolation voltage ensuring robust circuit protection
- Low coupling capacitance for improved noise immunity
Applications
- AC-in applications requiring high isolation
- General purpose signal isolation
- Industrial control systems
Procurement Notes
Verify the specific suffix (3X016) against official Vishay documentation to confirm the exact Current Transfer Ratio binning and packaging configuration. Ensure the procurement source provides valid RoHS compliance data as indicated in component specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Confirm that the DIP-4 package dimensions match the target PCB layout requirements before finalizing orders.
Selection Notes
Select this component when a high current transfer ratio is required for AC-input applications. The DIP-4 through-hole package is suitable for standard manufacturing processes. Consider the 5300 Vrms isolation rating for safety-critical designs. Compare the 100-320% CTR range against system gain requirements. Evaluate the 3.5 µs rise time for compatibility with signal frequencies. Ensure the 55 V collector-emitter voltage meets load switching needs.
Part Context
The SFH628A series belongs to Vishay's transistor output optocoupler family, designed for general-purpose isolation. The SFH628A-3X016 variant specifically targets applications needing higher current transfer ratios compared to standard bins. It complements other variants like the SFH628A-2 and SFH628A-4X016, which offer different CTR ranges. This part is distinct from the SMD SFH6286 series while sharing similar electrical performance characteristics.
Replacement Considerations
The VO617A-3X016 is documented as a recommended alternative with similar DIP-4 packaging and NPN output. Verify pinout compatibility and electrical parameter alignment, particularly the CTR range and isolation voltage, before substitution.
