Abstract:
An integrated circuit device for protecting circuits from transient electrical events is disclosed. An integrated circuit device includes a first bipolar junction transistor (BJT) and a second BJT cross-coupled with the first BJT to operate as a first semiconductor-controlled rectifier (SCR), where a base of the first BJT is connected to a collector of the second BJT, and a base of the second BJT is connected to an emitter or a collector of the first BJT. The integrated circuit device additionally includes a triggering device comprising a first diode having a cathode electrically connected to the base of the first BJT. The integrated circuit device further includes a third BJT cross-coupled with the second BJT to operate as a second SCR, where the third BJT has a collector connected to the base of the second BJT and a base connected to the collector of the second BJT.
