The SM4T33CA is a state-of-the-art Transil™ diode designed by the renowned semiconductor manufacturer, STMicroelectronics. This robust transient voltage suppressor (TVS) is engineered to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events.

Key Features

• Stand-off voltage: 33V - This parameter ensures that the device remains non-conductive under normal operating conditions, providing a margin of safety for the protected circuit.
• Peak pulse power: 400W (10/1000µs surge) - The SM4T33CA can absorb high levels of energy during transient conditions, safeguarding downstream components from damage.
• Low clamping factor: The device clamps the overvoltage to a safe level almost instantaneously, minimizing the risk to connected sensitive circuits.
• Low leakage current: Ensuring minimal power loss during normal operation, which contributes to the overall energy efficiency of the system.
• Fast response time: The diode reacts quickly to transient overvoltages, providing immediate protection to prevent damage to the electronic device.
• Bi-directional device: The CA suffix indicates that the diode is capable of protecting circuits from overvoltages in both directions, making it ideal for AC applications or bipolar signals.
