IHW40T120 - Infineon

IHW40T120 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Infineon provides a recommended PCB layout in their application note AN2019-03, which includes guidelines for thermal vias, copper thickness, and component placement to ensure optimal thermal performance.
• How do I select the right gate driver for this IGBT module?
  Infineon recommends using a gate driver with a minimum output current of 2A and a voltage rating that matches the IGBT's gate-emitter voltage. The driver should also have a suitable propagation delay and rise/fall time to ensure proper switching.
• What is the maximum allowed overcurrent and how do I protect the module from it?
  The IHW40T120 can withstand a maximum overcurrent of 2.5 times the nominal current for a short duration (typically 10ms). To protect the module, use a fast-acting fuse or a current sensing circuit with a shutdown mechanism to prevent damage from overcurrent conditions.
• How do I ensure proper cooling and heat dissipation for this module?
  Ensure good thermal contact between the module and the heat sink by applying a thin layer of thermal interface material. Use a heat sink with a thermal resistance of ≤ 0.5 K/W and a fan with a minimum airflow of 200 L/min to maintain a junction temperature below 125°C.
• What are the recommended storage and handling procedures for this module?
  Store the module in a dry, cool place (≤ 30°C, ≤ 60% RH) away from direct sunlight. Handle the module by the edges to prevent damage to the pins or internal components. Avoid bending or flexing the module during handling or installation.
