The SM15T33A is a robust transient voltage suppressor (TVS) diode from STMicroelectronics, designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This TVS diode is particularly suitable for applications where high reliability and surge capability are critical for system protection.

Key Features

• Stand-off Voltage: 33V - This device is designed to protect equipment operating at this nominal voltage level.
• Peak Pulse Power Dissipation: 1500W (10/1000μs) - The SM15T33A can absorb high levels of transient power, ensuring protection against surges.
• Low Clamping Voltage: The low clamping voltage ensures that the protected component sees a voltage within its tolerance during transient events.
• Uni-directional Device: It is designed to protect against transients in one direction, making it ideal for DC applications.
• Junction Passivation: Optimized for increased reliability and robustness against thermal and mechanical stresses.

Applications

The SM15T33A is versatile and can be used in a wide range of applications, including:

• Power supply lines
