Active production — no obsolescence risk on this BOM line
The VO617A-8X017T: ROHS3 compliance means no restricted-substance exemption expiry to track; the part ships with full material declaration for EU and global markets.
5300 Vrms isolation — what that means for the galvanic barrier
The 4-SMD Gull Wing package (supplier device package 4-SMD) places the optocoupler on the same PCB as the rest of the control electronics — no separate isolation slot needed, but the creepage distance between primary and secondary traces on the board still governs the system-level isolation rating.
CTR range and LED drive — sizing the input current
Current transfer ratio spans 130% minimum to 260% maximum at a forward current of 5 mA — this defines the LED drive budget: at 5 mA input, the output transistor can sink at least 6.5 mA (130% of 5 mA) and at most 13 mA (260% of 5 mA), which covers standard logic-level loads and relay coils. Typical forward voltage is 1.35 V at the test current; the absolute maximum DC forward current is 60 mA, so the LED is not the current-limiting element in most designs — the output side's 50 mA per channel ceiling is the tighter constraint.
Switching speed and temperature — where the part fits
Operating temperature range of -55 to 110 °C covers industrial enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics — the 110 °C ceiling gives margin above the 85 °C typical industrial ambient. Output transistor rated for 80 V maximum collector-emitter voltage and saturates at 400 mV maximum — the low saturation voltage keeps power dissipation in the output stage manageable when driving loads near the 50 mA limit.
