Hi

I have a problem identifying the diode that has failed in the Suzuki ECU.  The marking on the diode is 5-6L2, but I cannot find any documentation about this diode.  Does anyone know what can I buy a replacement for this diode? Is it an ordinary rectifier diode or a zener diode?

IDK (not really)
but 5.6v Zener 1/2watt or 1w.?

1N4734  (1w)
1N5339 (5w)

A and B suffixed parts are more accurate, B most.
seems like 1w sided to me....

wattage unknown. but MOUSER has plenty as usual....
