Product details

Isolation barrier and data-rate anchor

The FOD8163TR2 delivers 5000Vrms isolation in a 6-SOP package, which is the first check for any design that bridges a mains-referenced or high-voltage domain to a low-voltage controller. The 10Mbps data rate with 20ns typical rise and 10ns fall keeps the edge rates clean enough for most industrial fieldbus and encoder interfaces without excessive ringing. The open-collector Schottky-clamped output pulls down to a logic low without an external pull-up resistor, though a pull-up to the supply rail is still needed for the high state. Supply voltage spans 3V to 5.5V, so it works directly on 3.3V or 5V logic rails without a level translator.

Frequently asked questions

Is FOD8163TR2 compatible with 3.3V logic?

Yes. The supply range is 3V to 5.5V, so it runs on a 3.3V rail directly. The input side is a DC-coupled LED with a typical forward voltage of 1.45V and a max forward current of 25mA, which a 3.3V GPIO can drive through a series resistor.

What is the closest pin-compatible alternative to FOD8163TR2?

Within the onsemi family, the FOD8163 (without the TR suffix) is electrically identical but packaged in tube instead of tape-and-reel. For a cross-vendor alternative, look for a 6-SOP, single-channel, 10Mbps open-collector optocoupler with 5000Vrms isolation and 20kV/µs CMTI — the footprint is standard across several manufacturers.

What is FOD8163TR2's data rate?

10Mbps, with typical rise/fall times of 20ns and 10ns and max propagation delays of 90ns/80ns. This is fast enough for most industrial serial interfaces but not for gigabit links.
