Im designing a simple usb application and I used this USBLC6-2 for ESD protection and voltage surge on the Vusb. On the datasheet it says that the breakdown voltage is min 6V, however I did some test for this if this is for real. I input a 10V on the Vusb and I am expecting that the zener diode should clamp the voltage to 6V however I can measure 10V.
Can anybody explain why the input voltage was not clamped down to 6V as it is supposed to be clamp according to the datasheet? With regards with my PCB layout i just followed what the datasheet says
