It blew out and i can not use usb and firewire.
part name = E4P7
Code = DZ3

What is DZ stand for?? I guess it's a zener diode. but it has 3 pin....

I found, it's a zener diode. But why 3 pins??? Any idea?

It's a zener diode with e24 package.

The third pin is NC, this makes sense.

Thank you everybody.

Thanks for the info, I had the same part blow due to a faulty dock, however my iPod could still sync and charge ok.
I replaced it with a BZX84 4V7 but found that the original part is not E24 but SOT323 (almost half the size). however an E24 part can just about be shoehorned in.
