♦ Precautions
Owing to their small dimensions, the GaAs FET’s from which the F0601720B is designed
are easily damaged or destroyed if subjected to large transient voltages. Such transients
can be generated by power supplies when switched on if not properly decoupled. It is also
possible to induce spikes from static-electricity-charged operations or ungrounded equip-
ment.
