Consider the following statements regarding n-channel JFET: 1. The maximum drain current IDSS occurs when gate-to-source voltage VGS = 0 V and drain-to-source voltage VDS ≥ |VP|. (VP is pinch-off voltage). 2. For gate-to-source voltage VGS less than the pinch-off level, the drain current is 0 A. 3. For all levels of VGS between 0 V and the pinch-off level, the current ID will range between IDSS and 0 A, respectively. which of the above statements are correct ?
When VDS is the drain voltage and VDS(max) is the maximum drain voltage, the JFET will breakdown if:
