The recommended PCB footprint for GSIB1520-E3/45 is a rectangular pad with dimensions of 12.7 mm x 7.62 mm, with a thermal pad in the center. The pad should have a solder mask defined (SMD) and a non-solder mask defined (NSMD) area around the thermal pad.
To ensure reliable thermal performance, it is recommended to use a thermal interface material (TIM) with a thermal conductivity of at least 1 W/m-K between the device and the heat sink. Additionally, the heat sink should be designed to provide adequate airflow and heat dissipation.
The maximum allowed voltage derating for GSIB1520-E3/45 is 80% of the maximum rated voltage. This means that if the maximum rated voltage is 45 V, the maximum allowed voltage derating would be 36 V.
Yes, GSIB1520-E3/45 is suitable for high-frequency switching applications up to 100 kHz. However, it is recommended to consult the datasheet and application notes for specific guidance on layout, PCB design, and component selection to minimize parasitic inductance and ensure reliable operation.
During PCB assembly, the thermal pad of GSIB1520-E3/45 should be connected to a solid copper plane on the PCB to ensure good thermal conductivity. The thermal pad should not be soldered directly to the PCB, but rather connected using a thermal interface material (TIM) or a thermal tape.
