Hey all,
Trying to repair a 12v FM radio that has been wired in reverse polarity and caused the reverse polarity diode to go short circuit.
I removed the diode from the PCB and the radio works fine without the diode, but I wish to replace it anyway.
The problem is I am unsure of what type of diode or what rating etc I should purchase (cannot see any ratings on diode or PCB), other than it needs to be a PCB surface mount type.
I know what a diode does but not a whole lot else, do Ineed a Schottky, a Zener, something else...????
rs-components has about 8000 different types of diodes.
I have attached some photos.
The radio is a (GME gr300bt) .... according to the spec sheet its "10.8 – 15.6 V DC negative earth", and has a "6 amp 3 AG fuse".
Any assistance would be much appreciated!
Cheers
Bill
