Overview
The SFH615A-4X016 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and utilizes a PDIP-4 through-hole package. The device provides an insulation voltage of 5300 Vrms, ensuring robust isolation between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a power dissipation rating of 150 mW. The forward current is rated at 60 mA with a typical forward voltage of 1.65 V. The Current Transfer Ratio (CTR) ranges from 160% to 320%. Operating temperatures span from -55°C to +100°C.
Feature Summary
- Provides high-voltage isolation capability for signal transmission across potential barriers
- Utilizes an NPN phototransistor output stage for digital switching applications
- Designed for through-hole mounting in standard DIP-4 packages
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic families
- Power supply feedback loops requiring galvanic isolation
Procurement Notes
Verify the specific suffix X016 against the manufacturer's latest datasheet to confirm packaging details and regional compliance certifications. Ensure that the CTR range of 160-320% aligns with the design requirements for the intended application circuit. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a high CTR is required for efficient drive conditions. Compare the 5300 Vrms isolation rating against system safety standards. Consider the thermal management capabilities given the 150 mW power dissipation limit. Evaluate the switching speed characteristics if high-frequency operation is necessary for the target application.
Part Context
This part belongs to the SFH615A series of transistor output optocouplers. It shares similar pinouts and basic functionality with other variants in the family, distinguished primarily by their Current Transfer Ratio specifications and specific packaging or certification suffixes. The series is designed for general-purpose isolation tasks.
Replacement Considerations
The VO615A-4 is documented as a recommended alternative with comparable specifications. Verify pin compatibility and electrical parameter overlaps before substitution.
