DC to 50MBd Galvanic Isolation Fiber Optic Short Link

Currently Viewing:

The Avago Fiber Optic (FO) Short Link AFBR-395000RZ is a cost-effective galvanic isolation device capable of suppressing up to 50 kV of transient peak voltage on a single PCB. Based on 650nm fiber optic technology, the device is suitable for high transient voltage suppresion in applications such as inverters/drives, power electronics, or medical equipment.

The integrated receiver output of the AFBR-395000RZ is compatible with TTL logic families and operates any type of signal from DC up to 50 MBd. The device offers creepage and clearance distances, with a minimum of 101.16 mm.
