The SM6T68A is a robust Transil™ transient voltage suppressor (TVS) diode designed and manufactured by STMicroelectronics. It is engineered to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. With its bidirectional clamping feature, it is an ideal choice for safeguarding circuits in a variety of applications, including industrial, automotive, and telecommunication systems.

Key Features

• Stand-off Voltage: The SM6T68A is designed with a stand-off voltage of 58.1V, providing a suitable voltage threshold before clamping occurs.
• Peak Pulse Power: It can handle a peak pulse power dissipation of 600W (10/1000μs surge), ensuring reliable protection against high energy transients.
• Low Clamping Factor: The device offers a low clamping factor, which ensures that the voltage seen by the protected component remains within safe limits during transient events.
• Fast Response Time: With its fast response time to transient overvoltages, the SM6T68A is highly effective in protecting sensitive circuitry.
• Operating Temperature Range: The device operates effectively over a wide temperature range from -40°C to +150°C, making it suitable for harsh environments.
• Package: Available in a molded plastic, over glass passivated junction, the SM6T68A comes in a DO-214AA (SMB) package that is both compact and robust.

Applications

The SM6T68A is versatile and can be employed in numerous protective applications. These include:
