TVS diode with marker
Some components that are needed to be be in a certain direction (like most diodes, and some capacitors) there is a white line over the component to show the direction.
But why is this done for a P6KE43CA, Bi-Directional TVS Diode, 600W, 2-Pin DO-204AC like the picture below. Does the direction matter since it is bidirectional?

This is how mine look like from P6KE15CA; sorry for the bad picture, I do not have the TVS diodes at hand so used a screenshot crop from the page I bought them from:
