The SMP50-120 is a robust and high-performance Transil™ transient voltage suppressor (TVS) diode from STMicroelectronics, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. This device is specifically engineered to safeguard circuits by clamping unwanted high-voltage spikes and surges to a safe threshold, thereby preventing potential damage to connected components.

Key Features

• Stand-off Voltage: The SMP50-120 is characterized by a stand-off voltage of 120V, making it suitable for a wide range of applications that require this level of voltage protection.
• Peak Pulse Power: It offers an impressive peak pulse power dissipation of 600W (10/1000µs), ensuring high energy absorption capability during transient events.
• Low Clamping Voltage: The device features a low clamping voltage, which is essential for protecting sensitive circuit components without compromising their performance.
• Fast Response Time: With its quick response to transient overvoltages, the SMP50-120 is capable of reacting in a matter of nanoseconds, thus providing immediate protection against voltage spikes.
• Low Leakage Current: It has a very low leakage current, which helps to maintain the energy efficiency of the overall system by minimizing power loss when the device is in standby mode.
• Package: The SMP50-120 comes in a DO-214AA (SMB) package, known for its compact size and suitability for automated assembly processes.
