It provides 3750Vrms isolation in a compact 4-SOIC surface-mount package (4.40mm width, supplier device package 4-SSOP), making it suitable for space-constrained boards in industrial controls, power supplies, and PLC I/O modules. The current transfer ratio spans 80% to 160% at a forward current of 5mA, giving a predictable gain for driving logic inputs or low-current loads up to 50mA per channel and 80V output. The 3750Vrms isolation rating is the reinforcement dielectric withstand voltage for one minute per IEC 60747-5-5. This covers reinforced insulation requirements for mains-isolated AC-DC supplies and motor-drive interfaces where the buyer needs a single-device barrier without an external isolation transformer. The 80%–160% CTR window at 5mA forward current is a tighter bin than the wide 50–600% spread of generic parts like PC817 — it reduces LED drive current variation across reels, which matters when the output must reliably saturate a downstream logic gate or MOSFET gate driver over temperature. ## Temperature range and switching performance The 3µs typical rise and fall times and 6µs turn-on / 4µs turn-off are adequate for 50/60 Hz zero-crossing detection, relay coil drive, and low-speed digital isolation up to about 50 kbps — not for high-speed comms like I²C or CAN. The 400mV max Vce saturation at the output transistor keeps voltage drop low when driving a 5V or 3.3V logic input. ## Active lifecycle and compliance It is ROHS3 compliant.","metaTitle":"VOS617A-7T Optocoupler, 3750Vrms Isolation, 80-160% CTR","metaDescription":"VOS617A-7T single-channel transistor-output optocoupler with 3750Vrms isolation, 80-160% CTR at 5mA, -55°C to 110°C range.
