SEMTECH TVS Diode, 5V, 300W, 1.5pf, SOT-23-6, SMD, ESD Protection

The SEMTECH SRV05-4.TCT is a surge-rated transient voltage suppressor (TVS) diode array, engineered to deliver robust protection for high-speed data interfaces. Part of the RailClamp SR Series, this component is specifically designed to shield sensitive electronics connected to data and transmission lines from damaging overvoltage events such as electrostatic discharge (ESD), electrical fast transients (EFT), and lightning surges. Its sophisticated steering diodes channel transient energy safely to either the positive power supply line or to ground, while an internal TVS diode clamps overvoltage on the power line, ensuring downstream components remain secure.

A key advantage of this device is its extremely low typical capacitance of 3pF, which minimises signal integrity degradation, making it ideal for protecting high-speed data lines without compromising performance. It provides comprehensive protection for four I/O lines within a compact SOT-23-6 SMD package, offering a significant saving on valuable board space. The diode utilises reliable solid-state silicon-avalanche technology to achieve a low clamping voltage, ensuring sensitive circuits are protected effectively.
