How do I read Zener diode code

[Reek]

Can any one tell how to read zener diode code. I have T2D49 zener diode which I could not get the data sheet. I did search in google as well as cross referenced with major electronic part manufacturers. None of them have match with this code.

Yes, I am sure that's the letter written on the body of the diode. On the board where it was mounted printed as "ZD". The board is from TV power supply model: USP505M-42FN.

Could the manufacturer doesn't want to release the info?
