all blu ray diode pin outs not the same?

Then you should be fine, that voltage will go down with the diode attached.
MIND (discharge) THAT CAPACITOR!
What resistor value are you using? Something around 44 Ohm to give you 28ma, yes?

Sorry that is supposed to say doesn't. I am typing all this on my phone. So to clarify, the bottom pin does not make any contact with the case or heat sink. The middle pin (the one i am using for neg.) IS soldered to the diode case. The diode came from a Magnavox blu ray player (cheap black friday deal last year). Currently it is being driven at 8.2 volts and 28mA.

That doesn't tell us the model.

Peace,

Yes. I believe it is 47 ohm.

The blu ray player that the diode came from is a magnavox NB500MG1F

Every diode as at least 3 pins.

Positive pin.
Negative pin.
Grounding pin.

The "middle" pin you keep referring to that is connected directly to the case of the diode, is the grounding pin.

Heck of a first post there buddy. Welcome to LPF! Say, "Hi...", in the, 'Welcome', section.

Not all diodes have at least three pins. What about IRs? They sometimes only have two.


You know, I'm sure I read recently that there was a new diode or module out that was conversely wired. Was it a green that was case negative? I'm sure I read it on here though. Kind of off topic but relevant.

I'm supprised that nobody has asked this yet (he says it's from a bluRay player, but it sounds like he has a red diode,,,so)

Hey Ashenfang, what color do you get when you light 'er up?
If I recall correctly, top pin +, bottom pin - for blue's, top + middle (3 o'clock) - for RED's (and useless as it is, top -, middle + for I.R.'s)

Not so??

hi guy's great forum, i have a blu-ray ld like this,same pinout as most reds,it's from a toshiba bdx1100,sled is s8 0711k 412vt,running nicely on a 317 9v@115ma.any info on it would be appreciated

The Toshiba BDX1100 is a READER/PLAYER NOT a writer/burner.
I wouldn't push that diode any harder than you already are

Peace,
