WSTM2512QLR360FYR Frequently Asked Questions (FAQs)

  • Littelfuse recommends a PCB layout with a solid copper pour on the top and bottom layers, connected to the thermal pad of the device, to ensure optimal thermal performance. A minimum of 2 oz copper thickness is recommended.
  • Littelfuse recommends following the recommended soldering profile, using a solder with a melting point below 260°C, and ensuring the device is properly aligned on the PCB. A soldering iron with a temperature range of 220-240°C is recommended.
  • The maximum allowed voltage derating for the WSTM2512QLR360FYR is 80% of the rated voltage, as specified in the datasheet. Exceeding this derating may affect the device's reliability and performance.
  • The WSTM2512QLR360FYR is rated for operation up to 150°C. However, Littelfuse recommends derating the device's voltage and current ratings for temperatures above 125°C to ensure reliable operation.
  • The thermal pad should be connected to a solid copper pour on the PCB to ensure optimal thermal performance. A thermal interface material (TIM) can be used to improve thermal conductivity, but it is not required.
