The STMicroelectronics TVS Diode is a low clamping unidirectional single line TVS diode designed to protect the data line or other I/O ports against ESD transients. The device is ideal for applications where both reduced line capacitance and board space saving are required.Low clamping voltage of 3 V / +9 V IEC 61000-4-2 contact discharge at 30 nsUnidirectional deviceLow leakage current
