Littelfuse recommends a PCB layout with a solid ground plane, minimal lead length, and a heat sink for high-power applications. A 4-layer PCB with a dedicated power plane and a separate ground plane is also recommended.
To ensure reliability, Littelfuse recommends derating the device's current rating by 1.5% per degree Celsius above 25°C. Additionally, using a heat sink and ensuring good airflow can help reduce the junction temperature.
The QJ8016NH4RP can withstand a maximum surge current of 100A for 10ms, as per the IEC 61000-4-5 standard. However, it's recommended to consult the datasheet and application notes for specific surge current requirements.
Yes, QJ8016NH4RP can be used in a parallel configuration to increase the current rating. However, it's essential to ensure that the devices are matched in terms of voltage and current ratings, and that the PCB layout is designed to minimize current imbalance and thermal mismatch.
Littelfuse recommends using a fuse with a rating of 10A to 15A, with a blow time of 100ms to 200ms, to protect the QJ8016NH4RP from overcurrent conditions.
