1. Scope
Bi-directional MAX Guard ESD suppressors Array are specifically designed for high frequency circuit
applications (Ultra-low capacitance). They are specifically produced to protect sensitive electronic circuit
high-speed data lines against electrostatic discharge (ESD, as specified in IEC6100-4-2 and MIL-STD-883C).
The extremely low capacitances and leakage currents of these products are contributed by micro air space
discharge technology developed by TA-I.
