Forward Biasing a Diode A diode is a semiconductor device with a single pn junction and metal connections to leads. It has the ability to pass current in only one direction. 6 2024-01-15 WebA diode or a pn junction is forward biased when the positive side of external bias voltage is connected to the p region of the diode (the anode) and the negative side is connected to the n region (the cathode). In this condition, current is allowed through the pn junction.

WebWhen an external voltage is applied across the diode, with a sufficiently high potential on the anode relative to the cathode, the diode is forward biased, and current flows through the device. Absent such an applied voltage, the diode is reverse biased, and current does not flow. Forward bias. http://www.learningaboutelectronics.com/Articles/What-is-a-diode-connected-in-forward-biased
