    types of applications are described in detail in "Phase Control Using Thyristors" (AN1003). The circuit shown in Figure AN1007.1 provides random (anywhere in half-cycle), fast turn-on (<10 µs) of AC power loads and is ideal for applications with a high-duty cycle. It eliminates completely the contact
