A semiconductor diode is a fundamental component that controls current flow in electronic circuits. Match each diode term on the left with its corresponding characteristic or operational definition on the right.
- AnodeThe P-type semiconductor terminal represented by the base of the schematic arrow symbol
- CathodeThe N-type semiconductor terminal identified on physical axial components by a painted band or stripe
- Forward biasThe circuit condition where a positive voltage on the P-type material overcomes the barrier potential to allow conduction
- Reverse biasThe circuit condition where a positive voltage on the N-type material widens the depletion layer and blocks conduction
Answer
The Anode pairs with the P-type terminal represented by the triangle base, the Cathode pairs with the N-type terminal identified by the painted stripe, Forward bias pairs with the state allowing conduction when the P-type region is positive, and Reverse bias pairs with the state blocking conduction when the N-type region is positive.
A semiconductor diode consists of an anode (P-type side, represented by the base of the triangle symbol) and a cathode (N-type side, indicated by a band on the physical package and a vertical bar on the symbol). Connecting the positive supply to the anode creates forward bias, collapsing the depletion layer and allowing current conduction. Connecting the positive supply to the cathode creates reverse bias, expanding the depletion layer and insulating the circuit.
