Lovetube - In order to use this for a full wave bridge, you would have to buy a center tapped transformer. Then connect one end of the tranny to pin 3, the other end of the tranny to pin 1 and center tap to ground. Use pin 2 as the output of the rectifiers to the first filter cap, with it's minus connection back to ground (C.T.). - Pete

thanks Pete.
isn't that still a half wave rectifier ? normal full wave use 4 diodes .
i still don't see how these diode with common chatode can be wire to full wave using 2 of them which is 4 diodes but have common cathode

Lovetube - That's what the center tap is for. One side of the secondary conducts first, while the other side is blocked by it's diode. Then, the procedure reverses, the second side conducts, while the first side is blocked by it's diode. This happens on every half cycle, thus a 120 Hz ripple pattern. - Pete
