    SOT-23 SMD component with marking "SAs"

    Hi all,

    I've got an SMD SOT-23 component marked "SAs".
    Found BSS123 transistor on some websites which is most likely what I need, but on components listings it says it should be SAs, but in a datasheet it says SA marking (is the small s at the end a manufacturer?)
    Also found S-1206B2J-M3T1G 2.85V regulator with the same "SAs" marking, but looking at the pinout it must be something else as the regulator output (pin 3 of SOT-23) I have connected to ground.

    It's somewhere in a voltage regulation circuit. I have around 20-30V on pin 1, expect similar or less on pin 2, pin 3 is connected to ground as mentioned above.


    Could anyone point me in the right direction please?


    Many thanks,
    Greg

    Re: SOT-23 SMD component with marking "SAs"

    The lower case trailing 's' seems to indicate BSS123 is correct choice. Trailing lowercase letters are usually designators for a particular manufacturers fab facility where the smd was made.
