The SM6T18AY is a high-performance transient voltage suppressor from the renowned manufacturer STMicroelectronics, designed to provide state-of-the-art overvoltage protection. This product is part of the Transil™ series, which is specifically engineered to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

Key Features

• Stand-off Voltage: The diode has a stand-off voltage of 18V, making it suitable for a range of applications where this voltage level is required for efficient operation.
• Peak Pulse Power: It offers a peak pulse power dissipation of 600W (10/1000μs), ensuring robust protection against high energy transients.
• Low Clamping Voltage: With a low clamping voltage, the SM6T18AY ensures that the protected component will not be exposed to damaging voltage levels during transient conditions.
• Fast Response Time: The device reacts quickly to transient overvoltages, providing immediate protection to the connected circuitry.
• Unidirectional Device: As a unidirectional TVS, it is optimized for DC applications and offers protection in one direction, which is ideal for rectified power supplies.
