SC220Q

Exceeding the above specifications may result in permanent damage to the device or device malfunction. Operation outside of the parameters

specified in the Electrical Characteristics section is not recommended.

Notes:

() All voltage values in this section are with respect to PGND pin voltage.

(2) Tested according to JEDEC standard JESD22-A4-B.

(3) 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 JESD5 standards.
