An electronic device is described. The electronic device includes a body having a first surface and a second surface opposite the first surface. The first surface of the body is a first surface of the electronic the device. The electronic device also has a second surface opposite the first surface. A metal pattern is disposed on the second surface of the electronic device. The metal pattern includes a first electrode, a second electrode, and at least two thermal pads. The at least two thermal pads are electrically isolated from the first electrode and the second electrode, are located along opposite sides of the second surface of the electronic device, and have substantially identical shapes.
