10 Mbps open-collector optoisolator with 5 kVrms isolation
The FOD8163T is a single-channel optoisolator from onsemi that switches at 10 Mbps with an open-collector Schottky-clamped output. That data rate covers Profibus, DeviceNet, and many industrial backplane buses without stretching the bit period. The 5 kVrms isolation rating meets reinforced insulation requirements per IEC 60950-1, so this part can sit on the safety barrier in a motor drive or a medical patient interface without additional optocouplers.
Fast edges and high transient immunity for noisy environments
The 20 kV/µs minimum common-mode transient immunity means the output won't glitch when a 600 V IGBT switches next to the opto — a real concern in inverter stages where the ground plane bounces at tens of kV/µs.
Active production, ROHS3 compliant, 6-SOIC package
It is ROHS3 compliant, so no exemption expiry risk for EU-shipped products. The surface-mount footprint is the same as a standard SO-6 wide-body, so layout reuse from other 6-pin optoisolators is straightforward.
The output side runs from 3 V to 5.5 V, covering 3.3 V and 5 V logic families directly — no level shifter needed. The input LED forward voltage is 1.45 V typical with a maximum forward current of 25 mA, so a 3.3 V CMOS output with a 100 Ω series resistor drives it comfortably.
