Product Description
Semtech SM712.TCT is a 2-Element Bi-Directional TVS Diode with a peak pulse power dissipation of 400 W designed for transient voltage suppression in electronics systems. This diode features a 3-pin SOT-23 surface mount package, optimized for space-saving PCB layouts.
It provides bi-directional protection suitable for asymmetrical data lines, ideal for extended common-mode RS-485 interfaces. The device protects against Electrostatic Discharge (ESD) up to ±15 kV (air) and ±8 kV (contact), Electrical Fast Transient (EFT) pulses up to 40 A, and lightning surges up to 12 A.
With a minimum breakdown voltage of 13.3 V and maximum reverse stand-off voltage of 12 V, it ensures device reliability through low capacitance and solid-state silicon avalanche technology. The clamping voltage is rated at 26 V, limiting voltage spikes effectively during transient events.
This TVS diode operates in a wide temperature range from -55°C to 125°C, making it suitable for harsh environments. Its compact dimensions of 2.9 mm length, 1.3 mm width, and 0.95 mm height, and 3-pin configuration enable easy integration into modern electronic devices.
Common use cases include protection in industrial automation electronics, telecommunication equipment, automotive electronics, and other commercial electronic devices that require robust surge suppression and ESD protection.
Bi-directional diode for symmetrical transient voltage protection. 400 W peak pulse power with a maximum peak pulse current of 17 A. Low capacitance for minimal signal interference. Surface mount 3-pin SOT-23 package. Wide operating temperature range of -55°C to 125°C.
