SMCJ28CA-TR TVS Diode from STMicroelectronics

The SMCJ28CA-TR is a robust Transient Voltage Suppressor (TVS) diode designed by STMicroelectronics to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This TVS diode is specifically engineered to safeguard components which operate at a nominal voltage of 28V, providing reliable and fast overvoltage protection by clamping action.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 28V, which is the maximum voltage that can be applied while maintaining the diode in a non-conductive state under specified environmental conditions.
• Peak Pulse Power: It offers a peak pulse power dissipation of 1500 Watts for a 10/1000μs waveform, ensuring protection against high energy transients.
• Reverse Stand-off Voltage: The SMCJ28CA-TR has a reverse stand-off voltage that provides a margin of safety for the intended application, reducing the risk of device failure.
• Bi-directional Clamping: As a bi-directional TVS, the SMCJ28CA-TR can protect circuits from voltage spikes in both positive and negative directions, making it ideal for AC applications or where the polarity is reversible.
• Low Clamping Voltage: With a low clamping voltage, this diode ensures that the voltage spike is limited to a safe level, which is critical for protecting sensitive components.
• Fast Response Time: The device reacts in picoseconds to overvoltage events, providing immediate protection to the connected circuitry.
• ISO 9001 and ISO 14001 Certified: Manufactured by STMicroelectronics, a leader in the semiconductor industry, ensuring high-quality standards and environmental management.
