Abstract
A transient voltage suppressing device includes a plurality of fingers arranged laterally along a major surface of an epitaxial layer. The plurality of fingers includes fingers of a first type and fingers of a second type. The first type and second type of fingers each include a silicon controlled rectifier (SCR) region and a junction diode region. The plurality of fingers of the second type are conductively coupled together by a second metal layer disposed over top a first metal layer and electrically insulated from the first metal layer. The first metal layer conductively couples the SCR region and junction diode region of the first type of finger.
