Overview
The SFH601-4X009 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with base connection, housed in a 6-SMD surface-mount package. The device provides high isolation voltage of 5300 Vrms and supports a maximum collector-emitter voltage of 100 V. Key electrical parameters include a forward current of 60 mA, forward voltage of 1.65 V, and a current transfer ratio ranging from 160% to 320%. The unit operates within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- NPN phototransistor output with base terminal access for enhanced control flexibility
- Surface-mount packaging design suitable for automated assembly processes
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission across isolated ground planes
- Power supply feedback loop isolation
Procurement Notes
This component is officially listed as obsolete and no longer manufactured by the original equipment manufacturer. Availability is limited to existing stock or third-party distributors. Verification of part authenticity and storage conditions is critical due to the end-of-life status. Buyers should confirm lead times and warranty terms carefully when sourcing from secondary markets.
Selection Notes
Engineers considering this part must account for its discontinued status. Alternative components with similar electrical specifications, such as higher CTR ranges and comparable isolation voltages, should be evaluated. Ensure that any substitute matches the 6-SMD footprint and pin configuration to maintain board compatibility without redesign.
Part Context
The SFH601 series represents Vishay's line of transistor output optocouplers designed for general-purpose isolation applications. The SFH601-4X009 variant specifically offers a high current transfer ratio range, distinguishing it from lower gain variants like the SFH601-3. This series utilizes infrared LED technology coupled with silicon phototransistors.
Replacement Considerations
Public confirmed substitutes include Everlight Electronics Co Ltd part number CNY17-4S(TA). Users should verify that the substitute meets the required 5300 Vrms isolation rating and 100 V collector-emitter voltage specifications before implementation.
