With a 5.0V reverse standoff voltage and 19V clamping voltage at 47A peak pulse current, it is ideal for protecting 5V logic and communication interfaces. The device absorbs up to 890W peak pulse power (8\/20\u00b5s waveform) and withstands 30kV contact ESD per IEC 61000-4-2 Level 4. The low 300nA leakage current minimizes power consumption in battery-operated devices. AEC-Q101 qualification makes it suitable for automotive sensor and infotainment system protection.","working_principle":"1. Normal Operation: Under normal signal conditions (0 to 5V), the TVS diode operates in reverse bias below the breakdown voltage. The 300nA leakage current is negligible, and the 480pF capacitance has minimal impact on low-speed signals.\n2. ESD Event Clamping: When an ESD strike occurs, the voltage on the protected line rapidly rises. Once the voltage exceeds the breakdown voltage (~6V), the avalanche diode conducts heavily, diverting the ESD current to ground and clamping the voltage to 19V maximum.\n3. Surge Protection: For IEC 61000-4-5 surge events (8\/20\u00b5s waveform), the device absorbs up to 890W peak power by conducting the surge current while maintaining the clamping voltage, protecting downstream circuitry.\n4. Unidirectional Operation: The diode clamps positive transients through avalanche breakdown and negative transients through forward conduction, providing bidirectional protection for signals referenced to ground.","pin_description":"
