Hi, I've made a circuit to control some powerful RGB LEDs. The total load is less than 5A and it's powered by an 80VA 12V transformer through a Kbpc2502 rectifier that should be able to handle 200V at 25A.

I would have thought the rectifier could handle the required current with very little effort but, after burning my finger, I tested it and it's running at 103 degrees C. I know this is within the operating temperature range but it seems a bit excessive considering I'm running only a 5th of the rated current through it. I just want to check, is this normal?
