STMicroelectronics 1-Element Uni-Directional TVS Diode 600 W Surface Mount DO-214 SM6T56AY

STMicroelectronics SM6T56AY is a 1-Element Uni-Directional TVS (Transient Voltage Suppressor) diode designed to protect sensitive electronic circuits from voltage surges and transient spikes.

This diode features a robust surface mount DO-214 package (also known as DO-214AA or SMB) that facilitates easy installation on PCBs and provides efficient power handling within a small footprint.

With a peak pulse power dissipation capability of 600 W, the SM6T56AY diode effectively clamps voltage spikes up to 100 V, preventing damage to automotive and industrial electronic systems.

Its minimum breakdown voltage of 53.2 V and maximum reverse standoff voltage of 47.6 V make it suitable for protecting circuits operating around these voltage levels.

Designed to withstand a maximum peak pulse current of 40 A, it ensures reliable surge absorption during transient events in accordance with automotive surge standard ISO 7637-2 and electrostatic discharge standard ISO 10605.

The device operates over a wide temperature range from -55°C to 150°C and complies with the stringent automotive AEC-Q101 qualification, ensuring durability and reliability in harsh environments.

Its low maximum reverse leakage current of 1 μA makes it suitable for sensitive electronics where leakage can be critical. Typical applications include transient voltage suppression in automotive systems, industrial power electronic modules, and other circuits requiring robust surge protection.
