Abstract:
A method of forming a silicon carbide transient voltage suppressor (TVS) assembly and a system for a transient voltage suppressor (TVS) assembly are provided. The TVS assembly includes a semiconductor die in a mesa structure that includes a first layer of a first wide band gap semiconductor having a conductivity of a first polarity, a second layer of the first or a second wide band gap semiconductor having a conductivity of a second polarity coupled in electrical contact with the first layer wherein the second polarity is different than the first polarity. The TVS assembly also includes a third layer of the first, the second, or a third wide band gap semiconductor having a conductivity of the first polarity coupled in electrical contact with the second layer. The layer having a conductivity of the second polarity is lightly doped relative to the layers having a conductivity of the first polarity.
