For a 12V relay drawing 0.5A, a 1N4007 diode (rated for 1000V, 1A) would be a suitable and cost-effective choice for general applications.
69 72
For fast-switching applications, a 1N5819 Schottky diode (rated 40V, 1A) might be a better option due to its fast recovery time and lower forward voltage.
