Dear Si'ers, I am using a ATF-55143 Single Voltage E-pHEMT Low Current Low Noise device in an RF front end application. I need to make sure I am complient with contact ESD to +/-8KV. The device has an absolute maximum rating of +1V to -5V. Therefore the CM1213 I am using which is great as a very low capacitance ESD device, but of no use, since its break down voltage is +/-9V. Anybody got any ideas as to how to use the ATF-55143 device and ESD protect it without loading it with high capacitive ESD devices in my front end application.
