Bourns recommends a PCB layout with a solid ground plane, short and wide traces for the high-current paths, and a thermal relief pattern for the pads to ensure good heat dissipation and low inductance.
To ensure reliability, follow the recommended derating curves for temperature, use a suitable thermal interface material, and ensure good airflow around the device. Additionally, consider using a thermally conductive pad or heat sink to dissipate heat.
The PWR220T-20-4700J can withstand surge currents up to 100 A for 10 ms, but this may vary depending on the specific application and operating conditions. It's recommended to consult with Bourns' application engineers for specific guidance.
Yes, the PWR220T-20-4700J can be used in a parallel configuration, but it's essential to ensure that the devices are properly matched, and the PCB layout is designed to minimize current imbalance and thermal mismatch.
Store the PWR220T-20-4700J in a dry, cool place, away from direct sunlight and moisture. Handle the devices by the body, avoiding touching the leads or pads to prevent electrostatic discharge (ESD) damage.
