Can you please help me identify this electronic part?

Re: What is this electronic component?
Actually, as it says there on the board "PD", I would say both are some sort of power diodes.
The one on the left could be this one:
FAIRCHILD SEMICONDUCTOR - SS34 - DIODE, SCHOTTKY, 3A, SMD, DO-214

Re: What is this electronic component?
It looks like every component designator (R = resistor, C = capacitor etc.) is preceded by a 'P' for some reason.
Just noticed the one on the left, I imagine that will be a diode.
Maybe the 'P' is for Power board...System: HP xw6600 Workstation, 650W PSU | 2x Intel Xeon Quad E5440 @2.83GHz | 8x 1GB FB-DDR2 @ 667MHz | Kingston/Intel X25-M 160GB SSD | 2x 1TB Spinpoint F3, RAID0 | 1x 1TB Spinpoint F3, backup | ATI FireGL V7700 512MB | Sony Optiarc DVD +/-RW | Win 7 Ultimate x64 | 2x Dell UltraSharp U2410f | Dell E248WFPComment

Re: What is this electronic component?
uhm interesting.
Now, Am wondering if a bad capacitor could be causing the power to continuously recycle -causing a strange humming sound. It is a very low humming sound however.
thank you for your help thus far.Comment

Re: What is this electronic component?
I doubt the P signifies 'power Cap', 'Power resistor' etc. - look at that tiny resistor on the left, no way is that a power component.System: HP xw6600 Workstation, 650W PSU | 2x Intel Xeon Quad E5440 @2.83GHz | 8x 1GB FB-DDR2 @ 667MHz | Kingston/Intel X25-M 160GB SSD | 2x 1TB Spinpoint F3, RAID0 | 1x 1TB Spinpoint F3, backup | ATI FireGL V7700 512MB | Sony Optiarc DVD +/-RW | Win 7 Ultimate x64 | 2x Dell UltraSharp U2410f | Dell E248WFPComment

Re: What is this electronic component?
The board is from a laptop that gets power from an ac adapter which may explain why those resistors aren't very big? lol Am not a genius at electronics.Comment

Re: What is this electronic component?
Other than "p" stands for power, I have no other clue what it might stand for lol.Comment

Re: What is this electronic component?
Well, it is pretty convincing I mean. The "P" only show up near the battery area and the ac adapter socket area.Comment

Re: What is this electronic component?
That, if I'm not mistaken (At least the one on the right), is a tantalum capacitor."We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine! We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

Re: What is this electronic component?
Ok very nice. Now does anyone know how to read the codes on the capacitor that tell you what the ratings are? I might think about replacing themComment

Re: What is this electronic component?
Can you take a caliper and measure them?"We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine!

Re: What is this electronic component?
Caliper? sounds high tech. I don't really have a caliper but i think i can measure it in mm with an ordinary ruler. It is 8x5 mm.Comment

Re: What is this electronic component?
So I'm looking at the two big ones on the right-hand side, the ones with the markings:
330 6DS7 D...
I looked at a few pictures from various manufacturers, I just can't find anything. I'll try to keep looking.

Re: What is this electronic component?
PD = Power Diode
The others are PC.
Which I think must mean > Power Capacitor.

Re: What is this electronic component?
It looks like a Tantalum cap to me as well. Best solution is to check it with a multimeter out of the circuit - if it shows open circuit both ways when you measure it for continuity, then it's more than likely a capacitor. If it shows a [continuous] reading one way but not the other, then it's a diode. If it shows short circuit regardless of which way you test it, it's obviously a bad component.Originally posted by mockingbird View Post
Also, Tantalum caps usually commit a pretty nasty suicide when they go bad (i.e. they burn out - literally), so if it's a Tantalum, it's unlikely to be bad if it reads normal.
With that said, I would suggest you check the rest of the components in the charging circuit - particularly power rails being shorted to ground. The buzzing could be because there is an overload in the charging/power circuit somewhere.

PQ is for transistor. Just ignore the "P" prefix and you can see that this board has standard marking. C = capacitor, D = diode, R = resistor, Q = transistor, L = inductor.Comment
