It's hard to imagine many gardens without them: robotic mowers that whisper quietly as they roll across the lawn, keeping the grass nice and short. These intelligent, self-propelled devices have triggered a veritable revolution in lawn care in recent years. They take over the task of mowing the lawn fully automatically and allow us to keep our garden in perfect condition without having to lift a finger ourselves. And in the process, they save us a whole lot of time that we can use for other things.

In 1994, the Swedish company Husqvarna landed a coup with a small sensation: they had developed the first fully automatic lawn robot. Inspired by grazing animals in nature, the principle is to mow the lawn more often, but only in small steps. In 1995, the model went on sale for 5,500 DM (2,812 EUR).

Modern robotic mowers depend on reliable ESD protection to function trouble-free. Diotec's ESDALC208 in SOT-26 housing is an ESD protection diode that simultaneously protects four data lines. It is rated for ±15 kV/±8 kV according to IEC 61000-4-2 for air/contact discharge. In addition to use in robotic mowers, the ESDALC208 is ideal for portable electronics in industrial applications, remote controls for opening garage doors and smart home sensors for controlling lights, shutters or heating and air conditioning systems.
