|
A series of transient voltage suppressor diodes from Infineon is designed to protect antennas and front end devices from transient voltage events. The ESD101x and ESD103x diodes absorb electrostatic discharges (ESD), preventing damage to the antenna system while maintaining signal integrity.
The features for antenna protection include a symmetrical bidirectional configuration with a capacitance of 0.1pF to avoid mismatch and insertion loss. Both the ESD101x and ESD103x offer the high linearity required by TX and RX systems. Harmonic generation is minimised and intermodulation distortion is kept low to avoid in band interference and jamming.
With a typical leakage current of less than 0.1nA at working voltage, the diodes help to prolong battery life in portable electronic systems. The diodes can withstand repeated ESD strikes according to IEC61000-4-2 without any performance loss and react to multiple discharges within 1ns.
The ESD101x and ESD103x diodes are available in volume quantities in a TSSLP-2-3 package measuring 0.6 x 0.3 x 0.3mm.
