Re: Marking code 30A??

From which logic board? Brand? Model? Do you have a schematic?

It is from ON SEMICONDUCTOR. Looks like a SMB Schotkky diode with a 30A rating but need more details from your side.

It could be a On semiconductor 1.5SMC30AT3

Very nice hunting R_J. Thanks.

Agree on the p/n.

The original ONSEMI is no longer available but see the replacements at the bottom of this page for valid crosses:
