What is Thermal Management Solutions for IGBT?
Learn how specialized bimetallic substrates and heat spreaders improve thermal performance in high-power electronic applications.
Insulated Gate Bipolar Transistor (IGBT) power modules are the workhorses of modern power electronics, enabling efficient control of electrical energy in applications ranging from industrial motor drives to electric vehicle inverters.
The Thermal Challenge in IGBT Modules
IGBT modules dissipate substantial heat during operation due to conduction losses, switching losses, and reverse recovery losses. Without effective thermal management, this heat leads to elevated junction temperatures, increased losses, thermal stress, and potential failure.
Thermal Management Strategies
Direct Bonded Copper (DBC) Substrates
The substrate that mounts the IGBT chip plays a critical role in heat extraction. Raytron's DBC substrates feature copper layers directly bonded to aluminum nitride ceramic with thermal conductivity exceeding 200 W/m·K.
Bimetallic Heat Spreaders
Raytron's copper-clad aluminum heat spreaders offer significant advantages including high thermal conductivity at the interface, lightweight aluminum core, and cost-effective alternatives to solid copper spreaders.
