Semtech TVS Diode Array 2.8V Standoff 15V Clamp SOIC 8-Pin

The Semtech TVS Diode Array is an advanced EPD (Emitter Protected Diode) device specifically engineered for ESD and latch-up protection. It is designed to safeguard low voltage, state-of-the-art CMOS semiconductors from damaging transients caused by electrostatic discharge (ESD), cable discharge events (CDE), lightning, and other induced voltage surges. Constructed using proprietary EPD process technology, this device provides low standoff voltages alongside significant reductions in leakage currents and capacitance compared to traditional silicon avalanche diode processes.

Featuring an integrated low capacitance compensation diode, the device can be configured to protect a single unidirectional line or, when paired with a second unit, two high-speed line pairs. The low capacitance design ensures signal integrity is meticulously preserved in high-speed applications such as 10/100 Ethernet networks. Additionally, the flow-thru design minimises trace inductance and effectively reduces voltage overshoot associated with ESD events.
