摘要:
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.
