Semtech 4-Element Uni-Directional TVS Diode 200 W, 5-Pin SOT-353 SMF05.TCT

Semtech SMF05.TCT is a 4-Element Uni-Directional Transient Voltage Suppressor (TVS) diode designed to protect electronic circuits from voltage spikes and electrostatic discharges. Packaged in a compact 5-pin SOT-353 surface mount format, this TVS diode array offers a peak pulse power dissipation of 200 watts (tp = 8/20μs), making it suitable for robust transient protection in electronics.

The device features a common anode diode configuration and a uni-directional direction type, which is ideal for protecting sensitive data lines from ESD, latch-up, and EFT events compliant with IEC 61000-4-2 and IEC 61000-4-4 standards. It maintains low leakage current of 10μA and operates safely over a broad temperature range from -55°C to 125°C, ensuring reliable performance in demanding industrial and commercial applications.

The 5-pin SOT-353 package (2.1 mm length × 2.1 mm width × 1.1 mm height) hosts four diode elements that allow multi-line transient voltage suppression within compact PCB designs. Peak pulse current up to 12 amperes and a clamping voltage of 12.5 V provide effective protection against voltage surges and spikes, helping to safeguard connected circuitry.

Typical applications of this transient voltage suppressor include protection of telecommunications equipment, industrial control systems, and other electronic assemblies sensitive to electrostatic and transient events. The SMF05.TCT is part of Semtech's SMF series transient voltage suppressors known for reliability and compliance with key electrostatic discharge standards.

This product is efficient for industrial, electronic manufacturing, laboratory testing, and commercial electronics protection contexts. Peak pulse power dissipation of 200 watts ensures robust transient voltage suppression.
