Overview
The SFH615A-4X009 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a high current transfer ratio ranging from 160% to 320%. The device provides 5300 Vrms isolation voltage and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a forward current of 60 mA, and a power dissipation of 150 mW. It utilizes a 4-SMD鸥翼 (gull-wing) surface mount package.
Feature Summary
- Provides galvanic isolation between electrically separated circuits for signal transmission
- Features a high current transfer ratio suitable for efficient switching applications
- Designed with end-stackable construction for compact PCB layout
Applications
- Signal transmission between isolated control and load circuits
- General purpose digital signal isolation in industrial equipment
- Interface circuits requiring high isolation voltage ratings
Procurement Notes
Verify the specific suffix X009 confirms the 4-SMD gull-wing surface mount package configuration. Ensure the CTR bin matches the 160-320% requirement for the design. Confirm RoHS compliance status through the official datasheet as specifications may vary by production batch. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.
Selection Notes
Select this component when a high current transfer ratio is required for low input drive currents. The 5300 Vrms isolation rating makes it suitable for applications demanding robust safety barriers. Compare rise and fall times against system speed requirements. Verify that the 4-SMD footprint aligns with the target PCB design constraints.
Part Context
This device belongs to the SFH615A family of transistor output optocouplers. It shares functional similarities with other Vishay isolators but is distinguished by its specific CTR range and surface mount packaging. The family is designed for general-purpose isolation tasks where reliability and standard interface compatibility are prioritized.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and isolation voltage ratings before considering alternative manufacturers.
