F0601720BGaAs LED Driver IC ♦ 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. Electron Device Department
