Overview
The SFH615A-4X017T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and operates with a maximum collector-emitter voltage of 70 V and a continuous collector current of 50 mA. The device provides 5300 Vrms isolation voltage between input and output circuits. Electrical characteristics include a forward current of 60 mA, a forward voltage of 1.65 V, and a collector-emitter saturation voltage of 400 mV. The component utilizes a 4-SMD surface-mount package.
Feature Summary
- Provides high-voltage electrical isolation for signal transmission between isolated circuits
- Utilizes an NPN phototransistor output stage for digital switching applications
- Designed for surface-mount assembly to support automated PCB manufacturing processes
Applications
- Industrial control systems requiring galvanic isolation
- Signal interfacing in microcontroller-based embedded designs
- Power supply feedback loops for circuit protection
Procurement Notes
Verify the specific suffix X017T against official Vishay documentation to confirm the exact reel quantity and tape-and-reel specifications. Ensure the ordering part number matches the required package variant and compliance status. Cross-reference the manufacturer datasheet for any recent product change notices that may affect pinout or material composition before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount form factor is required for space-constrained designs. The 5300 Vrms isolation rating makes it suitable for applications demanding robust safety barriers. Compare the 40% to 80% current transfer ratio range against system gain requirements to ensure adequate signal integrity without excessive drive current.
Part Context
This component belongs to the SFH615 series of transistor output optocouplers from Vishay. The series offers various packaging options including through-hole DIP and surface-mount SMD configurations. The SFH615A-4X017T specifically denotes the surface-mount variant within this family, sharing core electrical performance metrics with other members while differing in physical mounting style.
Replacement Considerations
The VO615A-4 is listed as a recommended alternative with similar transistor output characteristics. Verify compatibility regarding package dimensions and pin spacing when substituting. Confirm that the replacement part meets the same isolation voltage and current transfer ratio requirements for the specific application.
