Abstract

Official abstract text for this publication.

A transistor package comprising: a substrate; a first transistor in thermal contact with the substrate, wherein the transistor comprises a gate; the substrate sintered to a heat sink through a sintered layer; an encapsulant that at least partially encapsulates the first transistor; and a Kelvin connection to the transistor gate.

First claim

Opening claim text (preview).

1 . A transistor package comprising: a substrate; a first transistor in thermal contact with the substrate; the substrate sintered to a heat sink through a sintered layer; an encapsulant that at least partially encapsulates the first transistor; and a Kelvin connection to a transistor gate. 2 . The transistor package of claim 1 , wherein the heat sink comprises fins and contact pads. 3 . The transistor package of claim 1 , further comprising a second transistor that is in series with the first transistor. 4 . The transistor package of claim 3 , wherein the first transistor is an insulated-gate bipolar transistor and the second transistor is a diode transistor. 5 . The transistor package of claim 3 , wherein the first transistor is a metal-oxide-semiconductor-field-effect transistor and the second transistor is a diode transistor. 6 . The transistor package of claim 1 , wherein the transistor package further comprises a copper cladding layer and the Kelvin connection is further connected to a busbar. 7 . The transistor package of claim 1 , wherein the first transistor comprises a gallium nitride or a silicon carbide wideband semiconductor. 8 - 14 . (canceled) 15 . An inverter comprising: a housing, wherein the housing is formed of a metal and is a heat sink; a transistor substrate; an insulated-gate bipolar transistor in thermal contact with the transistor substrate; an encapsulant that at least partially encapsulates the insulated-gate bipolar transistor; and a Kelvin connection to the transistor gate, wherein the transistor substrate is sintered to the housing through a sintered layer. 16 . The inverter of claim 15 , wherein the insulated-gate bipolar transistor comprises gallium nitride or silicon carbide. 17 . The inverter of claim 15 , further comprising a diode transistor in series with the insulated-gate bipolar transistor. 18 . The inverter of claim 15 , wherein the sintered layer comprises silver. 19 . The inverter of claim 15 , wherein the insulated-gate bipolar transistor comprises silicon. 20 . The inverter of claim 15 , wherein the housing comprises fins and contact pads.
