Wurth Elektronik 2-Element Uni-Directional TVS Diode Array, 4-Pin SOT-143, 3.3V, 4.5V Breakdown Voltage, 12A Peak 8240136

Wurth Elektronik 8240136 is a 2-element uni-directional transient voltage suppressor (TVS) diode array housed in a 4-pin SOT-143 surface mount package. It is specifically designed for the protection of sensitive electronics from electrostatic discharges (ESD) and transient voltage spikes commonly encountered in interfaces such as USB 2.0, HDMI, DVI, Ethernet, Firewire, and Serial Bus systems.

The diode array features a complex configuration with two elements per chip, offering enhanced suppression capabilities with a minimum breakdown voltage of 4.5V and a maximum reverse stand-off voltage of 3.3V. The device clamps voltage spikes efficiently with a clamping voltage of 6V, protecting downstream circuits from damage.

With a maximum peak pulse current rating of 12A and a test current of 1mA, this TVS Diode Array ensures reliable operation under high surge conditions. The device operates over a wide temperature range from -55°C to 125°C, making it suitable for demanding industrial and commercial applications.

The compact surface mount SOT-143 package measures 2.95mm in length, 1.3mm in width, and 1mm in height, enabling high-density PCB layouts. It has a maximum reverse leakage current of 5μA, minimizing power dissipation during normal operation.
