SM15T47AY Frequently Asked Questions (FAQs)

  • STMicroelectronics recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • Ensure proper heat sinking, use a thermal interface material (TIM) between the device and heat sink, and follow the recommended operating conditions and derating guidelines in the datasheet.
  • The maximum allowed voltage on the gate driver input is 20V, but it's recommended to keep it below 15V to ensure reliable operation and prevent damage to the internal ESD protection diodes.
  • Yes, the SM15T47AY can be used in a half-bridge configuration, but it's essential to ensure proper dead-time management and synchronization between the high-side and low-side switches to prevent shoot-through currents.
  • Use the thermal resistance (RthJA) and maximum junction temperature (Tj) ratings in the datasheet to calculate the maximum current rating for your specific application, taking into account the PCB layout, ambient temperature, and cooling conditions.
