The SM6T250CAY is a robust Transil™ transient voltage suppression (TVS) diode designed and manufactured by STMicroelectronics. This component is engineered to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It is particularly suited for use in space-constrained applications due to its compact SMB (DO-214AA) package.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 250V, providing a high degree of protection for electronic circuits from high transient voltages.
• Peak Pulse Power: It offers an impressive 600W (10/1000µs) peak pulse power dissipation capability, ensuring reliable performance during surge events.
• Low Clamping Voltage: With its low clamping voltage, the SM6T250CAY minimizes the stress on the protected component at the time of the surge.
• Bi-directional Device: As a bi-directional TVS, it is capable of protecting circuits from surges occurring in both directions along the protected line.
• Fast Response Time: The device responds to over-voltage events in less than 1 picosecond, providing immediate protection to the connected components.
• Low Leakage Current: It has a very low leakage current of less than 2 µA at stand-off voltage, contributing to energy efficiency in the application it is used in.
• Operating Temperature Range: The diode operates over a wide temperature range from -40°C to +150°C, making it suitable for various industrial and automotive applications.
• Compliance: It meets the ISO 7637-2 and ISO 16750-2 standards for automotive applications, ensuring reliability in harsh environments.
