Product Overview
Application context for VOS618A-3X001T (Vishay Semiconductor Opto Division · Optocouplers) — what the part is for, how it is typically used, and the design points buyers ask about first.
- Safety-Certified Isolation (Option 1): This variant includes the “X001” safety option making it compliant for applications requiring guaranteed insulation separation (e.g., per IEC standards).
- 100-200 % CTR Bin: High transfer ratio helps reduce LED drive current, improving efficiency and reducing system power consumption.
- Compact Tape-and-Reel Packaging: “T” suffix indicates reel packaging, facilitating automated surface-mount assembly flows.
The Vishay VOS618A-3X001T is a variant of the VOS618A series that meets safety agency approval under encoding “X001” (option 1) and is supplied in tape-and-reel format (“T”). It retains the same optical and packaging fundamentals: GaAs IR emitting diode, silicon planar phototransistor detector, in a 4-pin SSOP-4 half-pitch package.
This model again features the “-3” CTR bin (100 %–200 %) but adds the safety-rated insulation option (option 1) suitable for “safe electrical insulation” per IEC 60747-5-5.
The part is ideal when regulatory compliance and high reliability are required in industrial, medical or telecom isolation applications.
Features
-
High CTR (100–200 %) at low input current.
-
Safety-rated insulation (option 1) compliant with IEC 60747-5-5 and other agency approvals (UL, cUL, VDE) for high isolation.
-
Low profile SSOP-4, half-pitch package.
-
80 V collector-emitter voltage rating.
-
Isolation test voltage of 3750 VRMS.
-
Low coupling capacitance suitable for high common-mode transient immunity.
-
Material categorisation and compliance ready.
Specifications
(Same base specifications as described in the previous section for VOS618A series, with CTR bin “-3” as 100 %–200 %. Refer to previous section for full spec.)
Applications
-
Safety-critical signal isolation in industrial control systems.
-
Telecom line interfaces where isolation and low input drive are required.
-
Battery-powered portable devices requiring both regulatory approval and compact packaging.
-
Medical / office-machine interfaces where safe electrical insulation is mandated.
-
PLC input/output interface circuits requiring assured isolation performance.
