enter image description hereI need to identify what I think is a voltage regulator. It is a TO-220 package with 023499 at the top and 8509 below it with KAG below that. Can anyone help with this? It is in a battery charger.

    \$\begingroup\$ Could you post a photo of said device. Preferably one detailed enough to see the markings. A manufacturers logo would be useful as @brhans said. \$\endgroup\$ Mar 31 '15 at 17:27

it looks to me like a Motorola thyristor produced in the ninth week of 1985. The K A G refer to the Cathode (K), anode (A) and Gate(G) pins.

The number is possibly a house number rather than a public one.
