Development of 2-in-1 SiC module "DOT-247" - Achieving high design flexibility and power density -

ROHM Co., Ltd. (headquarters: Kyoto City) has developed the "DOT-247," a 2-in-1 SiC module ideal for industrial equipment applications such as PV inverters, UPS, and semiconductor relays. While retaining the versatility of the "TO-247," which is widely used in power devices, the new module offers high design freedom and power density.

DOT-247 has a configuration of two TO-247 packages joined together, and by incorporating large chips, which was structurally difficult with TO-247, and by using a unique internal structure, it has achieved low on-resistance. Furthermore, by optimizing the package structure, thermal resistance has been reduced by approximately 15% and inductance by approximately 50% compared to TO-247. This allows for 2.3 times the power density when using TO-247 in a half-bridge configuration, and enables the realization of an equivalent power conversion circuit in approximately half the volume.

The new products using DOT-247 are available in two topologies, half-bridge and common source, and are compatible with a variety of circuit configurations, including NPC circuits and DC-DC converters. Using it in these power conversion circuits, which incorporate multiple discrete components, reduces the number of components and mounting area, significantly contributing to application miniaturization and reducing mounting and design work.
The lineup includes four part numbers (SCZ40xxDTx) with a 750V withstand voltage and four part numbers (SCZ40xxKTx) with a 1200V withstand voltage.
