Isolation rating and where it fits
The 6N135SVM: The 5000Vrms isolation is the deciding parameter for this optocoupler — it provides galvanic separation between a low-voltage control side and a high-voltage power stage, typical in motor drives, industrial PLC I/O modules, and switch-mode power supply feedback paths. The 8-SMD Gull Wing package is a surface-mount footprint that reflows onto a PCB without through-hole assembly, though the gull-wing leads are visible for post-solder inspection.
Current transfer ratio and switching speed
The current transfer ratio spans 7% minimum to 50% maximum at a forward current of 16 mA. That 7% floor is the gain the designer must guarantee across temperature and device variation — if the downstream logic needs a 2.5 V swing into a 10 kΩ load, the 8 mA output current capability per channel sets the pull-up resistor ceiling. Typical turn-on time is 230 ns, turn-off 450 ns, fast enough for 1 MHz data rates but not for high-speed isolated communication like Ethernet.
Active production and sourcing
onsemi lists the 6N135SVM as Active and ROHS3 compliant. Pricing and stock are confirmed at quote time against your BOM quantity.
Temperature grade and environment
Rated for -40°C to 100°C operating temperature, this optocoupler suits industrial enclosures, outdoor telecom cabinets, and under-hood automotive auxiliary circuits — not extended military or downhole environments. The DC input type means the LED is driven by a steady forward current, not an AC waveform.
