The SM4T12CA is a high-quality Transil™ transient voltage suppressor (TVS) diode from STMicroelectronics, designed to provide state-of-the-art overvoltage protection for sensitive electronics. This bidirectional TVS diode is specifically engineered to safeguard voltage-sensitive components from destruction or degradation due to transient voltage events, such as electrostatic discharges (ESD), electrical fast transients (EFT), and other induced surges.

Key Features

• Stand-off Voltage: The SM4T12CA has 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 400W (10/1000μs), this device can handle significant transient power spikes without compromising its integrity or the protection of the circuit it serves.
• Low Clamping Voltage: The low clamping voltage ensures that, in the event of a voltage surge, the voltage presented to the protected component will not exceed a safe level, thus preventing damage.
• Fast Response Time: The fast response time of the SM4T12CA ensures that it reacts quickly to transient events, providing immediate protection to downstream components.
• Package: Available in an SMA package, the SM4T12CA is compact and suitable for high-density circuit board designs.

Applications

The SM4T12CA is ideal for a variety of applications where transient voltage protection is necessary. These include:

• Power supply lines
• Communication systems
• Automotive electronics
• Industrial control systems
• Consumer electronics
