It is designed for industrial control, PLC I/O modules, motor drive feedback, and medical equipment where signal integrity across a potential barrier is required. ## CTR range and what it drives The current transfer ratio (CTR) is specified at 100% minimum and 200% maximum, measured at a forward current of 1 mA. This means the output transistor can sink at least as much collector current as the LED forward current, with headroom up to 2×. For a design driving a 5 mA load, a 1 mA LED current guarantees saturation across temperature and over the life of the part. ## Switching speed and output ratings Typical rise and fall times are 5 µs and 7 µs respectively; turn-on and turn-off times are 5 µs and 8 µs. These figures suit low-to-moderate speed applications such as 10 kHz PWM feedback, relay coil drive, or status LED indication, but not high-speed serial isolation. The output transistor is rated for 80 V maximum collector-emitter voltage and 50 mA continuous output current per channel, covering most 24 V industrial logic and 12 V automotive loads with margin.","metaTitle":"VOS618A-3X001T Optocoupler, 3750Vrms, 4-SSOP, Vishay","metaDescription":"Vishay VOS618A-3X001T optocoupler: 3750Vrms isolation, 100-200% CTR at 1mA, 80V output, -55 to 110°C.

The difference is the CTR bin: the VOS618A-3X001T guarantees 100–200% CTR at 1 mA, while the VOS618A-2X001T has a lower CTR range (typically 63–125% at 1 mA). For designs requiring higher drive margin or lower LED current, the -3 bin is preferred; for cost-sensitive builds where CTR margin is less critical, the -2 bin may be a drop-in alternate after verifying saturation at minimum CTR."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/VOS618A-3X001T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/VOS618A-3X001T when reusing this data.
