LL34 SMD Zener diode package 1/2W Multiple Value
SMD diodes LL34 have a range of anode/cathodeidentifiers. Sometimes it’s easiest to just use a multimeter to test for polarity. Turn the multimeter to the diode setting (usually indicated by a diodesymbol), and touch each probe to one of the LEDterminals. … Diodes certainly aren’t the only polarized component.
