Overview
The SFH615A-4X001 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and is housed in a DIP-4 package for through-hole mounting. The device provides high isolation voltage of 5300 Vrms, ensuring robust signal transmission across isolated circuits. Key electrical parameters include a collector-emitter voltage (Vceo) of 70 V, maximum collector current (Ic) of 50 mA, and forward current (If) of 60 mA. The typical current transfer ratio (CTR) ranges from 100% to 200%. Operating temperatures span from -55°C to +100°C, with power dissipation rated at 150 mW.
Feature Summary
- High insulation voltage capability of 5300 Vrms for safe galvanic isolation
- NPN phototransistor output configuration for standard switching applications
- Compliant with UL, VDE, and RECOGNIZED safety standards for industrial use
Applications
- Industrial control systems requiring reliable signal isolation
- Power supply feedback loops for voltage regulation
- Microcontroller interface circuits for level shifting and protection
Procurement Notes
Verify the specific CTR binning requirements against the datasheet, as the SFH615A series may have multiple variants with different gain ranges. Confirm that the DIP-4 package and through-hole mounting style align with the PCB design constraints. Ensure compliance with RoHS directives if required by the final product specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when high isolation voltage and moderate speed are required for single-channel applications. The NPN output is suitable for sinking current loads. Consider the thermal management capabilities given the 150 mW power dissipation limit. Compare with other Vishay models like the VO615A if surface mount options or different CTR ranges are needed for the specific circuit design.
Part Context
This component belongs to the Vishay SFH615A series of high-reliability optocouplers. It is designed for applications demanding long-term stability and safety certification. The series includes various packaging options and CTR bins to accommodate diverse design needs while maintaining consistent performance characteristics across the product line.
Replacement Considerations
Direct substitutes include the VO615A-4X001, which shares similar electrical characteristics and pinout. Verify compatibility with any alternative parts regarding isolation voltage ratings and physical dimensions before integration.
