The SM4T12CAY is a state-of-the-art Transil™ diode designed and manufactured by STMicroelectronics, a global leader in semiconductor solutions. This robust transient voltage suppressor (TVS) is engineered to protect sensitive electronic equipment from voltage transients induced by system inductance, load dump, and lightning, making it an essential component for a wide array of applications.

Key Features

• Stand-off Voltage: The device is designed to provide a stand-off voltage of 12V, making it suitable for a range of applications where this voltage level is critical for operation.
• Peak Pulse Power: With a peak pulse power dissipation of 400 W (10/1000 µs), the SM4T12CAY can handle significant power surges, ensuring the protection of downstream components.
• Low Clamping Voltage: It offers a low clamping voltage relative to its stand-off voltage, which means that it can effectively clamp transient overvoltages to a safe level without compromising the performance of the protected circuit.
• Fast Response Time: The device reacts quickly to transient overvoltages, providing immediate protection to sensitive components.
• Low Leakage Current: It is characterized by a low leakage current, ensuring minimal power loss during normal operation and contributing to the energy efficiency of the overall system.
• Package: Housed in an SMB (DO-214AA) package, the SM4T12CAY offers a compact footprint suitable for space-constrained applications.
