Hey all,
I need to clamp a transient voltage (around 5-10 us) which can rise up to 20V +ve and 20 V -ve i.e. 40 V pp to +/- 5V. The frequency of this voltage varies from 10 to 15 MHz.
I was thinking of the p6ke39ca bi-directional diodes to clamp this voltage. One end of the diodes would be connected to the signal and the other ends would be connected to +5 and -5 V respectively as seen below
---|----|------> signal | | D D | | | |
+5V -5VThe maximum current in the system is 2A. My question is: would this be an effective scheme and would this need multiple diodes for operation ?
