| Working Peak Voltage |
The Bourns CD143A-SR3.3 is a steering TVS diode array designed for ESD protection of data lines in portable electronics. It features a working peak voltage of 3.3V and a clamping voltage of 7V at 1A (8.2V at 10A). The device dissipates peak pulse power up to 200W (8/20μs) and handles peak pulse current up to 12A. It provides ESD protection per IEC 61000-4-2 up to ±30kV (air and contact).
The CD143A-SR3.3 protects two unidirectional channels and includes power line protection. Typical capacitance is 4.5pF at 0V and 1MHz, making it suitable for high-speed interfaces. Reverse leakage current is 5μA maximum (1μA typical). The device is offered in a surface mount SOT-143 package and operates over -55°C to +125°C temperature range.
Applications include Ethernet (10/100/1000 Base T), Firewire, USB, portable electronics, and video/graphic cards. The component is RoHS compliant and halogen free.
