DiodesZetex 1-Element Uni-Directional TVS Diode 400W 2-Pin DO-214 SMAT70A-13-F

DiodesZetex SMAT70A-13-F is a high-performance 1-element uni-directional transient voltage suppression (TVS) diode with a peak pulse power dissipation rating of 400W. It is designed primarily for surface mount application on printed circuit boards where effective transient voltage protection is critical in electronic and electrical systems.

This TVS diode is packaged in a compact DO-214 surface mount package featuring two pins, which facilitates easy soldering and integration into protective circuits. The diode configuration is single element uni-directional, optimized to clamp voltage spikes and protect sensitive components from transient events caused by ESD, inductive load switching, or lightning surges.

With a minimum breakdown voltage (Vbr) of 77.8V and maximum reverse stand-off voltage (Vwm) of 70V, the SMAT70A-13-F effectively limits voltage spikes to a clamping voltage (Vc) of 100V at its rated peak pulse current of 3.5A. It sustains transient disturbances with a peak pulse power dissipation capability of 400W for a 10/1000μs waveform. The device maintains a low maximum reverse leakage current of 5μA, ensuring energy efficiency and minimal quiescent current during normal operation controls.

The diode’s operating temperature range from -55°C to 150°C further extends its suitability for harsh industrial and commercial electronics environments. Physical dimensions of 4.6mm length, 2.92mm width, and 2.1mm height make it highly adaptable for compact PCB layouts. Although it lacks specific automotive certification, it meets all fundamental electrical and thermal parameters required for transient voltage suppression in a wide range of electronic products.

Common applications for the SMAT70A-13-F include protection of power supplies, data lines, telecommunications equipment, industrial controls, and general electronic circuitry against high-energy transient surges and electrostatic discharge events. Its uni-directional property ensures it is ideally used where voltage spike clamping in a single polarity direction is essential.
