Abstract: A circuit protection component including a crowbar device for protecting electronic devices from transients is generally disclosed. The circuit protection component may include a steering diode bridge and a crowbar device electrically connected to the steering diode bridge. The crowbar device may have a base and an emitter formed on a first layer, the first layer defining a breakdown voltage, which when exceeded allows current to pass under the emitter and out the device through a hole formed in the emitter.

Abstract: A low voltage protection device that includes a silicon substrate comprises an inner layer of a first dopant type. The device also includes a first outer layer of a second dopant type disposed adjacent a first surface of the inner layer and a second outer layer of the second dopant type disposed adjacent a second surface of the inner layer opposite the first surface. The device further includes a first mesa region disposed in a peripheral region of a first side of the low voltage protection device. The first mesa region includes a first area that includes a peripheral portion of a cathode of the low voltage protection device, the cathode formed by diffusing a high concentration of dopant species of the first type on a first surface of the silicon substrate, and a second area comprising a high concentration of diffused dopant species of the second type.
