With +\/-8kV IEC 61000-4-2 contact discharge withstand and low 12V clamping voltage, it protects sensitive ICs from electrostatic discharge events. The ultraminiature UDFN package (0.65x1.0mm) is ideal for space-constrained mobile and wearable applications where PCB area is at a premium.","working_principle":"The XCA204A0K1MR operates as a bidirectional transient voltage suppression (TVS) diode array. Under normal operating conditions (signal voltage within VRWM = 5.5V), the diodes present a very high impedance and ultra-low capacitance (0.5pF), making them essentially invisible to high-speed signals. When an ESD event or voltage transient exceeds the breakdown voltage (VBR > 6.5V), the TVS diodes avalanche, providing a low-impedance path to divert the transient current away from the protected IC. The clamping voltage is limited to 12V maximum at 3A, well below the damage threshold of most ICs. The bidirectional design ensures symmetrical protection for AC signals. The low 0.1uA leakage current at VRWM prevents battery drain in always-on applications. Each channel provides independent protection between the I\/O line and ground, with minimal crosstalk between adjacent channels.","pin_description":"\n
