It accepts supply voltages of 3V to 3.6V on one side and 4.5V to 5.5V on the other, so it can bridge a 3.3V MCU to a 5V fieldbus transceiver without external level shifters. Each channel can sink or source 10 mA at the output, and the typical rise/fall time of 6.5 ns keeps the signal edge clean at 15 Mbps. The propagation delay max of 60 ns both ways gives predictable timing for synchronous serial links like SPI or RS-485. ## Common-mode transient immunity and temperature range The minimum common-mode transient immunity is 20 kV/µs, which means the part can reject fast voltage spikes between input and output grounds — essential in motor drives, inverters, or any environment with high dV/dt switching noise. The 8-SOIC package (3.90 mm width) is a standard footprint for optoisolators, simplifying layout reuse. ## Active lifecycle and sourcing posture The part is offered in Tape & Reel (TR) and Cut Tape (CT) options, which matches standard pick-and-place assembly for the 8-SOIC package. Availability is confirmed per RFQ — no stock-holding claim is made here. For reel quantities (typical for production runs) or smaller cut-tape samples, submit a request against your BOM line. The dual supply range and 15 Mbps data rate mean this part can serve as a drop-in for many older 10 Mbps optoisolators where speed margin is needed.","metaTitle":"FOD8012AR2 onsemi Optoisolator – 15 Mbps, 3750 Vrms, 8-SOIC","metaDescription":"onsemi FOD8012AR2 dual-channel push-pull optoisolator: 15 Mbps data rate, 3750 Vrms isolation, 20 kV/µs CMTI.
