SiC417
Notes:
a. This device is ESD sensitive. Use of standard ESD handling precautions is required.
b. Calculated from package in still air, mounted to 3 x 4.5 (in), 4 layer FR4 PCB with thermal vias under the exposed pad per JESD51 standards.
Exceeding the above specifications may result in permanent damage to the device or device malfunction. Operation outside of the parameters
specififed in the Electrical Characteristicsw section is not recommended.
