The recommended footprint and land pattern for SMAJ200A can be found in the Littelfuse application note AN9313, which provides guidelines for surface mount assembly of TVS diodes.
To ensure reliability in high-temperature applications, it's essential to follow the recommended derating curves for voltage and current, and to consider the device's thermal resistance and power dissipation. Additionally, ensure that the device is soldered correctly and that the PCB is designed to minimize thermal stress.
While SMAJ200A is primarily designed for transient voltage suppression, it can be used in high-frequency circuits. However, the device's capacitance and inductance should be considered, and the circuit should be designed to minimize resonance and ensure stability.
To select the correct SMAJ200A variant, consider the maximum voltage, current, and power requirements of your application. Refer to the datasheet and consult with Littelfuse's application engineers if necessary. Additionally, consider the device's package type, polarity, and screening level (e.g., commercial, industrial, or automotive).
SMAJ200A is designed to provide ESD protection up to ±30kV, exceeding the IEC 61000-4-2 standard. However, the device's ESD protection capabilities may vary depending on the application and PCB design. Consult the datasheet and application notes for more information.
