Littelfuse recommends a PCB layout with a thermal pad connected to a large copper area to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended, and the thermal pad should be connected to a ground plane or a heat sink.
To ensure reliability, Littelfuse recommends following the derating curves provided in the datasheet, using a suitable thermal interface material, and ensuring good airflow around the device. Additionally, consider using a thermally conductive adhesive or thermal tape to improve heat transfer.
The LOC110PTR has a surge current rating of 100 A for 10 ms, as specified in the datasheet. However, it's essential to note that the device can withstand higher surge currents for shorter durations, but this may affect its long-term reliability.
Yes, the LOC110PTR can be used in a parallel configuration to increase the current rating. However, it's crucial to ensure that the devices are properly matched, and the PCB layout is designed to minimize current imbalance and thermal differences between the devices.
Littelfuse recommends using a fuse with a rating of 1-2 A, depending on the specific application and current requirements. A slow-blow fuse is recommended to ensure that the fuse doesn't trip unnecessarily during inrush currents or other transient events.
