New Wolfspeed Module Family in Single Switch Topology – TM Series

These are advanced automotive power modules designed for modern inverter systems. They are based on silicon carbide (SiC) technology and built in a single‑switch topology, providing exceptional efficiency, high reliability, and design flexibility.

The TM module family uses the latest Wolfspeed SiC MOSFET transistors, offering a compact baseplate‑less design, low parasitic inductance, and high thermal robustness.
All of this makes the TM series an ideal fit for e‑mobility, industrial drives, and electric aviation, setting a new standard in power conversion by combining high performance with durability and ease of integration.
