Bias voltage connections: positive to anode (A); negative to cathode (K).
■ The bias voltage must be greater than the barrier potential.
■ Barrier potential: 0.7 V for silicon.
■ Majority carriers provide the forward current.
■ The depletion region narrows.
■ Bias voltage connections: positive to cathode (K); negative to anode (A).
■ The bias voltage must be less than the breakdown voltage.
■ There is no majority carrier current after transition time.
■ Minority carriers provide a negligibly small reverse current.
■ The depletion region widens.
