The banded end of the rectifier.
Connect to the positive half-wave output in the example.
This page uses the KiCad convention 1 = cathode, 2 = anode. The manufacturer identifies polarity by the band, not numeric package pins.
Conventional forward current enters here and leaves the cathode.
Connect to the isolated low-voltage AC source in the example.
Forward voltage depends on current and temperature; 0.7 V is only the teaching assumption used below.
