I've been trying to identify the following part. It is marked with the following logo:
I haven't come across this logo before, but the "P" and the fact that it is a likely a diode (see below) brings Panasonic to mind.
The part is as shown:
Its reference designator is "D12" so it is likely a diode array of some sort. The markings are: logo + "0551 STA". It appears to be connected between a transformer and a Broadcom 10/100 BASE-TX (ethernet) transceiver, specifically the BCM5221 (Datasheet).
Can anyone identify the part or the logo as shown?
Thanks in advance.
