Latest Patents

One of Cartmell's latest patents is a bi-directional transient voltage suppression (TVS) device. This innovative device includes a semiconductor die that features a first avalanche diode in series with a first rectifier diode, connected cathode to cathode. It is electrically coupled in an anti-parallel configuration with a second avalanche diode in series with a second rectifier diode, also connected cathode to cathode. All the diodes of the TVS device are integrated on a single semiconductor substrate. The design incorporates a low resistivity buried diffused layer that shunts most of a transient current away from a portion of the epitaxial layer, thereby reducing the clamping voltage relative to the breakdown voltage. The TVS device is packaged as a flip chip with four solder bump pads.
