OPA 365 + FTZ869 as laser driver



I want to use the application of opa 365 to make a driver for laser diode .  and when i saw a nice laser diode driver design, coming from Texas Instruments's  SBEA001 (the "Laser Diode Driver 1") by Neil P. Albaugh ,  i thought it is a good design for laser driver .  but i can not find the exact datasheet for FTZ869 . i think it is wrong in the design and that transistor should be FZT869 . Am i right ?
