Hi all
I'm trying to work out the value of a zener diode (CT6 in attached diagram) that blew when I accidentally connected the power to my mp3 player reverse polarity.
Attached is a diagram of the power-input cicuit that i buzzed out. These are the first few components near the power connector on the player that connects to the wall power pack which puts out 5v at 2A.
The part in question is a two leg SOD323 package with JW printed on it.
At this stage I'm looking at replacing it with a 5.6v zener diode of same package size. I'm guessing this zener is used to protect the circuit from voltage spikes.
Can anyone comment on the function of the zener diode (CT6 in diagram) and a possible value for it.
regards
James
