hi Iceskater
have a look at the attached pic and u will find enough info for this code.
u can also download the attached pdf file which contains many useful information about all SMD devices
Regards
according to the data i have the code QP for SMD device refers to a device called CMDZ7L5 and produced by CSC and in package SOD323 and it's a Zener .
250mW, IZ =0.5mA , 7.5V
but u said the package contains 6 Pins , so i don't expect it to be the same .
so , i guess this is not the code for this device , but it's produced by QP and u can visit their web site here :
