The recommended PCB layout for optimal thermal performance of the LCC120STR includes a thermal pad on the bottom of the device, a solid copper pour on the top and bottom layers, and thermal vias connecting the top and bottom layers. This layout helps to dissipate heat efficiently and reduce thermal resistance.
To ensure the reliability of the LCC120STR in high-temperature applications, it is recommended to follow the derating guidelines provided in the datasheet, use a suitable thermal interface material, and ensure good airflow around the device. Additionally, consider using a thermally conductive substrate and a heat sink if necessary.
The LCC120STR can withstand surge currents up to 100A for 8.3ms, as specified in the datasheet. However, it is recommended to consult with Littelfuse Inc or a qualified engineer to determine the suitability of the device for specific surge current requirements.
Yes, the LCC120STR can be used in parallel to increase the current rating, but it is essential to ensure that the devices are properly matched and that the PCB layout is designed to minimize current imbalance and thermal mismatch between the devices.
The recommended fuse type and rating for overcurrent protection of the LCC120STR depend on the specific application and operating conditions. However, as a general guideline, a fast-acting fuse with a rating of 1-2 times the maximum expected current is recommended. Consult with Littelfuse Inc or a qualified engineer for specific recommendations.
