These figures place the part firmly in the realm of discrete I/O isolation, relay drivers, and low-frequency signal coupling — it will not support high-speed communication links or fast PWM loops above roughly 10kHz. The 80V output voltage rating and 50mA output current per channel give headroom for driving small loads or interfacing with 24V industrial logic levels. Operating temperature spans -55°C to 110°C, qualifying it for industrial environments including outdoor telecom cabinets and factory-floor enclosures where ambient temperatures can reach 85°C with internal heating. The 400mV maximum Vce saturation at the rated output current keeps conduction losses low enough that no heatsinking is needed in the 4-SSOP package. ROHS3 compliance covers the EU RoHS exemption regime without any restricted substances above the threshold limits. The 4-SOIC (4.40mm width) body and 4-SSOP supplier package designator are the same physical footprint — the SSOP variant is simply the thinner-profile version of the same SOIC outline.","metaTitle":"Vishay VOS615A-4X001T Optocoupler, 3750Vrms, 4-SSOP","metaDescription":"Vishay VOS615A-4X001T phototransistor optocoupler, 3750Vrms isolation, 160-320% CTR at 10mA, 4-SSOP.
