    Abstract: An apparatus and method for enhanced transient blocking employing a transient blocking unit (TBU) that uses at least one depletion mode n-channel device interconnected with at least one depletion mode p-channel device. The interconnection is performed such that a transient alters a bias voltage Vp of the p-channel device and a bias voltage Vn of the n-channel device such that the p- and n-channel devices mutually switch off to block the transient. The apparatus has an enhancer circuit for applying an enhancement bias to a gate terminal of at least one of the depletion mode n-channel devices of the TBU to reduce a total resistance Rtot of the apparatus. Alternatively, the apparatus has an enhancement mode NMOS transistor and a TBU connected thereto to help provide an enhancement bias to a gate terminal of the enhancement mode NMOS.

    Abstract: This invention relates to achieving high breakdown voltage and low on-resistance in semiconductor devices that have top, intermediate and bottom regions with a controllable current path traversing any of these regions. The device has an insulating trench that is coextensive with the top and intermediate regions and girds these regions from at least one side and preferably from both or all sides. A series capacitive structure with a biased top element and a number of floating elements is disposed in the insulating trench, and the intermediate region is endowed with a capacitive property that is chosen to establish a capacitive interaction or coupling between the series capacitive structure and the intermediate region so that the breakdown voltage VBD is maximized and on-resistance is minimized. A second series capacitive structure disposed in a second insulating trench can be employed to terminate the device.

    Abstract: An apparatus and a method for uni-directional and bi-directional transient blocking. The uni-directional apparatus has a depletion mode n-channel device at its input and a normally closed relay, e.g., a micro-electro-mechanical (MEM) relay, interconnected with the depletion mode n-channel device and the input in such a way that at a predetermined current value the transient causes the normally closed relay to switch into an open state and apply a bias voltage Vn on the depletion mode n-channel device that is sufficiently high to switch it “off” thus block the transient. An analogous arrangement at the output taking advantage of the same or a second relay renders the apparatus bi-directional. The structure of the apparatus and the method of operation ensure a reliable and repeatable trip current Itrip and render the apparatus very robust and feasible for low-cost manufacture.
