Semtech 2-Element Bi-Directional TVS Diode 400 W, 3-Pin SOT-23 SM712.TCT

Semtech SM712.TCT 2-Element Bi-Directional TVS Diode is engineered for transient voltage suppression up to 400 Watts peak pulse power, ideal for protecting sensitive electronics from voltage spikes and surges in industrial, communication, and electronic applications. This device is a bi-directional type, providing symmetrical protection to data lines, particularly for extended common-mode RS-485 signals ranging from +12V to -7V. This makes it suitable for use in industrial automation, instrumentation, and power supply lines.

The compact SOT-23 package with 3 pins allows efficient surface mounting on printed circuit boards with limited space. It features low capacitance and a low clamping voltage of 26V to reduce stress on circuit components during transient events.

Compliance with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Lightning) standards ensures robust protection against electrostatic discharges up to ±15kV, fast transients of 40A, and lightning surges up to 12A, suitable for harsh industrial environments and laboratories requiring reliable surge protection.

Designed to operate reliably from -55°C up to +125°C, this TVS diode maintains performance across a wide temperature range. The product features two elements per chip, enabling bi-directional protection with a peak pulse current of 17A, while its maximum reverse stand-off voltage is 12V.

Dimensionally small at 2.9mm length, 1.3mm width, and 0.95mm height, the diode facilitates integration in compact electronic assemblies where space constraints are critical. The maximum reverse leakage current remains low at 20μA, contributing to energy efficiency.

This device is widely applicable across industries including telecommunications, industrial control, power electronics, and commercial electronic equipment to safeguard components from damage caused by transient voltage spikes.

Package contains a single SM712.TCT diode, perfect for PCB assembly lines needing high quality, reliable transient voltage suppression components. Choose Semtech SM712.TCT for durable, effective surge protection in demanding electronic and industrial circuits.
