Product details
Overview
SFH6750-X007T from Vishay Semiconductors is a surface-mount, gull-wing DIP-4 optocoupler with reinforced insulation, 890 Vpeak maximum operating insulation voltage (VIORM), 1669 Vpeak routine test voltage (VPr), and >10⁹ Ω insulation resistance at 500 V. It delivers galvanic isolation for AC/DC power supply feedback loops, IGBT gate drive interfaces, and industrial PLC input modules.
For engineers reviewing the SFH6750-X007T datasheet, SFH6750-X007T pinout, SFH6750-X007T application, or SFH6750-X007T equivalent, key selection criteria include its VDE-certified reinforced insulation per DIN EN 60747-5-5, 0.9 mm max standoff height, >8 mm creepage/clearance, and compatibility with reflow soldering profiles for automated SMT assembly.
Technical Context
The SFH6750-X007T integrates an AlGaAs infrared LED coupled to a silicon phototransistor in a single DIP-4 package. Its isolation barrier meets VDE 0884-5 requirements with partial discharge <5 pC at 1669 Vpeak (1 s), enabling use in safety-critical secondary-side feedback paths.
Designed for surface mounting, the X007 option specifies gull-wing leads with 0.9 mm maximum standoff height and creepage/clearance distances exceeding 8 mm-meeting IEC 60950 requirements for reinforced insulation up to 400 VRMS or DC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VO615A-9X007T | Higher CTR range (200–400 %) vs. SFH6750-X007T's unspecified CTR; identical VIORM, package, and VDE certification | Better suited for low-drive-current interfaces where input LED current is constrained below 5 mA | Select VO615A-9X007T when higher sensitivity is needed without increasing input drive capability |
| PC817XNIP0X | Lower VIORM (5000 VDC isolation rating but only 3750 VRMS working voltage); non-VDE certified; same DIP-4 gull-wing form factor | Limited to basic insulation applications (e.g., consumer adapters), not suitable for medical or industrial safety-critical designs | Choose PC817XNIP0X only for cost-sensitive, non-safety-certified systems where 890 Vpeak working voltage is unnecessary |
Compared with VO615A-9X007T and PC817XNIP0X, the SFH6750-X007T provides verified VDE-reinforced insulation at 890 Vpeak with guaranteed >8 mm creepage-making it the only option qualified for IEC 62368-1 Annex Q and UL 62368-1 end-equipment certification in mains-connected systems.

FAQ
What safety certifications does the SFH6750-X007T hold?
The SFH6750-X007T is certified per DIN EN 60747-5-5 (VDE 0884) for reinforced insulation, with partial discharge <5 pC at 1669 Vpeak (1 s routine test). It meets IEC 60950 requirements for 400 VRMS systems and supports end-equipment compliance with IEC 62368-1 and UL 62368-1. The SFH6750-X007T documentation confirms all test conditions and limits without requiring external validation.
Does the SFH6750-X007T require special soldering processes?
Yes-the SFH6750-X007T must be soldered using reflow methods only (vapor phase, infrared, or hot gas), per CECC 00802. Tin-lead solder is prohibited as it degrades isolation performance. The device supports two reflow cycles maximum, with cooling to 25 °C between cycles. The SFH6750-X007T's gull-wing leads and 0.9 mm standoff are optimized for this process.
What is the maximum operating insulation voltage (VIORM) for the SFH6750-X007T?
The SFH6750-X007T has a maximum operating insulation voltage (VIORM) of 890 Vpeak, validated per DIN EN 60747-5-5. This value defines the highest continuous peak voltage the isolation barrier can sustain during normal operation while maintaining safety integrity. The SFH6750-X007T datasheet specifies this parameter unambiguously in its safety maximum ratings table.
Can the SFH6750-X007T replace through-hole optocouplers in existing designs?
No direct PCB replacement is possible-the SFH6750-X007T uses a surface-mount gull-wing DIP-4 footprint (7.62 mm pitch, 0.9 mm standoff), unlike through-hole variants. Layout changes are required to accommodate SMT pads, thermal relief, and clearance rules. However, the SFH6750-X007T offers identical electrical behavior and superior isolation specs versus legacy through-hole equivalents like SFH610A-X001.
What is the creepage and clearance distance of the SFH6750-X007T?
The SFH6750-X007T provides >8 mm creepage and >8 mm clearance distances, as defined in Option 7 documentation and confirmed in Vishay's application notes. These dimensions satisfy reinforced insulation requirements for 400 VRMS systems per IEC 60950 and eliminate the need for PCB slotting or conformal coating. The SFH6750-X007T achieves this via optimized leadframe geometry and body molding.
