Product details

20 Mbps digital isolation with push-pull output

The FOD8173TR2 is a single-channel digital optocoupler from onsemi rated for 20 Mbps data rate with a push-pull, totem-pole output stage. The 55 ns max propagation delay and 7 ns typical rise/fall times keep signal edges clean for isolating fieldbus interfaces, PLC digital inputs, or gate-drive feedback paths.

Isolation and transient immunity for industrial noise

Reinforced isolation of 5000 Vrms meets the creepage and clearance requirements for motor-drive and power-supply safety barriers. The 20 kV/µs minimum common-mode transient immunity means the output does not glitch when the isolated side sees a fast voltage step — a common failure point in IGBT/SiC gate-drive circuits where the high-side reference jumps hundreds of volts in nanoseconds.

Frequently asked questions

Does FOD8173TR2 have a push-pull output?

Yes, the output type is push-pull, totem pole. This means it can both source and sink current without an external pull-up resistor, unlike open-collector optocouplers.

What is the difference between FOD8173 and FOD8173TR2?

The base product number is FOD8173. The TR2 suffix indicates Tape & Reel packaging — the die and electrical specs are identical. The FOD8173TR2 is the reeled version for automated pick-and-place assembly.
