    hello,

    i have a sot23 with reference "CR"22, on the case i see A6W
    What it could be ?
    Also, it is near to something similar to a buzzer, that's named "LS"1, but of square shape with small hole in the middle, that measures 43ohm.

    thanks

    thanks, it could be, i de-soldered and measured it, act as diode. LS1 is really a buzzer.

    CR has been used for diodes since semiconductor diodes have been around
    it sorta depends on country of origin and the learning history of the circuit designer
    as to if CR or D is used

    Same with transistors -- T, TR, Q

    and voltage regulator IC's -- VR, SR, IC

    can get confusing for new comers to the hobby ;)
