The SM30T6.8AY is a robust Transient Voltage Suppressor (TVS) diode from STMicroelectronics, designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This TVS diode is part of the SM30TY series, which is well-known for its capability to absorb high transient power and energy within a compact package.

Key Features

• Stand-Off Voltage: The device has a stand-off voltage of 6.8V, making it suitable for a wide range of applications where this level of protection is required.
• High Surge Capability: With its ability to handle surge currents up to 3000W (10/1000μs), the SM30T6.8AY is an excellent choice for protecting against severe voltage spikes.
• Low Clamping Voltage: The low clamping voltage ensures that the protected circuitry is exposed to minimal stress under transient conditions.
• Unidirectional Protection: As a unidirectional TVS diode, it is specifically designed to protect one polarity overvoltage events, making it ideal for DC power supply applications.
• Package: It comes in an SMB (DO-214AA) package that is both compact and provides a good balance between board space and thermal performance.
• Compliance: The device meets the ISO 7637-2 and ISO 16750-2 standards for automotive applications, ensuring reliability and performance under harsh conditions.
