The 6KE series is a type of diode know as TVS (transient Voltage Surpressor) it protects the regulator and other sensitive circuits from high input voltage spikes. (the type of spikes normally of very short duration caused by high current switching or lightning strikes)
these diodes are designed to dissipate these spikes as heat, as yours is so badly burnt i would have to assume that what ever power supply you connected to is wrong or faulty. it looks like a much higher supply than 12V has been applied to it.
RS sell the diodes here http://uk.rs-online.com/web/c/?searchTerm=6KE&sra=oss
good luck
