這個也不太好認喲,有測試過嗎?

沒有測試過程,但是供貨商講為封裝地不同,但是我不認同此講法

另外一款的Marking點為印刷的,而且不清楚---最好不要用,現在假的太多了.

據我用過的仙童產品,印字都比較小

In general, Power Diss. can be impacted by Gate-Source Voltage, have you noted 6679Z and 6679, The value of "Z" is -25/+20V, but the value of "6679" and "AZ" is -25/+25V, It's hard to check out if you only review thru. the picture, because actually, Fairchild has many many suppliers and that will be different if the packing location is different;
One more, you'd better to check the requirement of your project and according it to select AZ or Z or 6679 only.

我覺得應該是左邊那個吧,據我所看過的喲,你這塊產品是用到什么上的,我們公司也有做FSC的,好像沒有見過這個型號!

我也覺得左面是真的.我用過仙童的IC,好多水貨.

我做仙童.用左邊那個.我做電源及加熱類的配件.仙童主要是場效應.及IGBT.只做原裝環保的.

Thanks
