The base terminal (D terminal) is connected to the output transistor base. It is also connected to the control monolithic IC. Do not, therefore, apply an external voltage in operation. *2. SDH04 have two or three terminals of the same function (VB, Out1, Out 2, GND). The terminals of the same function must be shorted at a pattern near the product.
