  • Page 5 1. Introduction The purpose of this evaluation board is to demonstrate the high-switching performance of Cree 3 Generation Silicon Carbide (SiC) Metal Oxide Semiconductor Field-Effect Transistors (MOSFETs) in a 7L D2PAK package. The new surface-mount device (SMD), specifically designed for high voltage MOSFETs, has a small footprint with a wide creepage distance of 7mm between drain and source.
  • Page 6 A block diagram of the evaluation board is shown in Figure 2. Besides the two Cree 900V, 120mΩ (C3M0120090) SiC MOSFETs (Q1 and Q2), there are two onboard isolated gate driver circuits to drive both Q1 and Q2. There are four power connectors (CON1, CON2, CON3, and CON4) for connecting to the +DC link, -DC link, and midpoint.
