Additional Details

The 1SMC33A has a standoff voltage of 33V, meaning it will not conduct under normal operating conditions below this voltage. Its breakdown voltage is typically around 36.7V. At its peak pulse current, the clamping voltage is approximately 53.3V. It is available in a surface-mount SMC (DO-214AB) package. The operating temperature range typically spans from -55°C to +150°C. This TVS diode is designed for high reliability and stability. Proper handling and soldering techniques, as recommended by Central Semiconductor Corp, are important to ensure optimal performance and longevity.
