6. θ

should be confirmed with heat sink thermal resistance. SOT89 exposed pad soldered to minimum recommended landing pads (see Package Outline

Dimension section) on 2”x2” two-layer 2oz.copper FR4 PCB with thermal vias in the exposed pad connecting to the copper flood on the bottom layer.

7. The V

value is in D.C voltage measurement. The V

may vary with coils in A.C. voltage measurements.
